Every time I save it pops up a warning the the Illustrator file was modified outside of Illustrator. It is NOT TRUE. Fix this absolutely frustrating JUNK WARNING!

Same issue happened since updated to Illustrator 2020 (24.0) om Catalina version 10.15

Same problem, introduced when I updated to Illustrator 2020 on High Sierra

Happens with MAC too! Getting message every 2 min or so. Tried restarting both Illustrator and computer; did NOT fix. Happens when working from server AND off laptop as well.

Same bug on Mojave 10.14.6 all time

Same issue, Illustrator 2020 on Mojave. Has other issues since updating to 2020 such as workspace files corrupted and Photoshop crashing. Other strange buggy things happening.

Bad update.

Yes, same bug here on Mojave.

I'm having this issue with Illustrator 2020 on Mojave.

add my name

I continue to have the same issue. I've upgraded to v.24 w/ no change.

I am running Catalina 10.15.1 with Illustrator 2020 v. 24.0 and having this issue a lot. Doesn't matter if I'm saving to my desktop or to the server.

I'm really tired of seeing it when *I* created the the file and no one else has access to it.

Same here—running 24.0 on Mojave 10.14.6 saving to Dropbox.

v24. Same message here.

Illustrator 24.0. Every time I save, this popup appears. again.

This issue is back with Illustrator CC 2020 (24.0)

I recently updated to AI v24.0 (High Sierra) and just started getting this message. VERY annoying.

My computer automatically updated to Illustrator 2020, and I received this same message. Now, whenever I go to export my file as a PDF, the colors in the PDF are completely different than what I have in my AI file. My client needs the file soon, and this is really stressing me out.

Add my name to the pile of people constantly getting this message with Illustrator 2020. Mac OS Mojave 10.14.6 I'm on Illustrator 24.0 No notices for further updates in my Creative Cloud application. If it helps my files are being mirrored with Time Machine.
