It would appear that with the Ai (beta) it is back to functional as expected.

This is exactly what I'm experiencing. I'm glad Adobe is aware. Thanks.

Please Adobe, write either in the patch note or here when an update to Illustrator will correct this bug. I'm still on the previous version as I cannot afford the hasle with my workload.

Thank you, just tried and text behaves normally. Not sure if disabling this feature will become an issue in other ways, but I trust your people are working on a permanent fix.

Thanks again for the workaround.

When I select a text box and change the font, I double-click to enter the text box to continue typing in the new font, BUT... it does not type in the newly-selected font. It switches back to the previously selected font. I do not know how this happens and I cannot figure out if I did something to make it do this.

Have no way of taking a screen video of this occurence.

Really impractical bug.

Also having this issue. Completely wiped illustrator then reinstalled and it worked for a few files then the issue started again. mine happens with text boxes from elements in my library's, I have always had "missing glyph protection " on and this was not an issue last week and nothing has been updated since.

Hi there,
In V. 29.1 if I open a previously created document and I change the font of a text element, a problem occurs when I go to edit the text.

As you see in the screenshot, when I try to edit the text, the font of the newly typed text changes to the originally used font.

Insanely time consuming to make text changes or corrections as a result.

I was writing a sentence all of a sudden the font type change to another font type

It's a relief that turning off "Missing Glyph Protection" fixed this for now but this was driving me crazy and I hope it gets fixed soon.

This is an incredibly resource-wasting problem. Simple text edits on files with lots of text have gone from normally annoying to absolutely hours-wasting.

While it was being approved another issue have risen about this.

If you use variables, create/import a bunch and then you decide to change a font for a text block involved in datasets - you are scrwd:
- change a block font settings
- switch to another dataset
- switch dataset back (or a third one no matter)
you have the initial font in this text block back.

And this is really bad.

Create a text object (area/not area - does not matter). Chose font you want to use (say Font1, bold) and type. Select object afterwards, and set new font for it (say Font2, regular). Text will change it's appearance (as expected). Then select entire text using type tool and then delete it. In this empty text object type a new text. it will appear with Font1 bold style (Font2, regular expected).
Please see screencast attached.

Noticed in the latest version 29.1. Not sure about 29.0.

It may happen and may not. More often it happens. I cant clearly say what exactly triggers this behavior.

Whenever I have a text zone with ANY font, if I input new text, it will ALWAYS output the new text in Arial Bold, regardless of the original text font (whether it's Arial Regular, or some custom font).

This is more than frustrating, it's kind of a blocking issue, since I cannot edit any text without having to manually set again the font for the text zone.

To reproduce:
- Create a text zone, type some text
- Set the text zone to be another font than Arial Bold (you can choose Times New Roman or Futura)
- Edit the text, the new text will be Arial Bold

Expected:
New text should be the same properties as the rest of the text zone

I'm experiencing this as well. I searched for it a few days ago and didn't see this thread but I'm happy to see this is getting some attention. My fonts are changing to other fonts I have been using as soon as I start typing to edit. I am in the midst of some heavy production work where I need to be efficient and this is getting very annoying.

What's happening for me is if I copy and paste text boxes and change it to a new font I'm using, and then edit the text in the text box, it reverts back to the previous font I was using. Or if I create a new text box, edit the text and set the font as I'd like it, as soon as I type anything new into the text box it changes to a different font in my file.

I just saw the temporary fix suggested so I'm trying that now.

This problem is getting annoying. It wastes a lot of time editing those missing glyphs. It’s a problem I haven’t seen in several years.

This was happing to me too with latest update. Very annoying when working with lots of type. But the suggestion of checking off the Glyphs pref Type prefs seems to have fixed it.

I am using Version 29.1 of Illustrator on a Mac.

I want to replace all of Font A in my document with Font B. I use the Find/Replace Font tool to select Font A and hit Change All after selecting Font B. This works as expected and all my text written in Font A turns into Font B.

However, when I try to type anything new in the existing text boxes, all the new text reverts back to Font A. When I try to create a new text box, the font by default uses Font A even if I change it to Font B or any other font.

Hello, j'ai ouvert une discussion aujourd'hui à ce propos. J'ai le même souci et suis d'accord avec Michael Karst, ça n'affecte que les fichiers créé avant la version 29.1
Je ne peux pas revenir à une version antérieure (ce que m'a préconisé un employé Adobe) car je travaille à distance et tous mes collègues ont fait leurs mises à jour. Pourtant aucun d'eux n'a ce souci...

When editing existing text in Adobe Illustrator 2025, the font formatting of the text resets to the default font (Myriad Pro) instead of retaining the original formatting of the text box. This issue persists even when the text box is selected using the Selection Tool (V) before editing. This behavior did not occur in previous versions of Illustrator and disrupts the workflow.
