Hello, this problems is continuously happening to me. I have a lot of artboard (900+) and some times I need to rename a few consecutive. Every time but without a clear pattern, the first one edited come back to its previous name. Sometimes in a few seconds after the last edit, sometimes a few hours later. It happens both on Windows and MacOS.

I have been having this problem repeatedly. I cannot understand the rhyme or reason for this issue. Even saving the working file. I have tried to carefully track why this would be happening but I cannot and it is disastrous for my workflow.

When i give an Artboard a new name, and in the same action presses [Ctrl] [A] and then [Ctrl] [C] to use the same namestructure for other Artboards, the new name disappears and the old comes back.

The newest version of Illustrator (and previous version) both have a glitch that occurs when trying to re-name artboards in a previously saved document that has multiple artboards. After changing the names of each artboard and then going to "export for screens", the name of the first artboard will revert to it's previous name before exporting. All other artboards will retain their new name. In order to correct this, I must save the file, and then re-name the first artboard a second time and save again. After doing this, all artboards will export correctly.

Yes, same problem i also

This problem drives me crazy. Please fix it.

I can confirm the same exact bug, not with all files but a lot of them no longer save the names when I reopen the file...

Other notes:
1- artboard names from other peoples file do not open
2- artboard names in all of my own files are gone (unless I uninstall illustrator and go back to old version)
3- tried to uninstall illustrator, reboot, delete the Adobe cache folder, install illustrator fresh

problem persists.
NOTE: that the name disappear after saving, closing and then re-opening the file.

Yes, same problem, also... In the new version of Illustrator - CC 22.1 the ARTBOARD NAMES do not save at all. To reproduce open a new illustrator document, set up 10 artboards, NAME THEM, save the document, close it, re-open the document, the names are GONE. Also, when opening illustrator files that PREVIOUSLY had artboard names, all names are gone. They have been replaced with generic artboard names. To fix the issue switch back to a previous version of illustrator, ie: 20 or below, and the artboard names are back and they stay.

same problem here, i used the prerelease (22.0.1) and it worked, i use the final version now. still worked for me, but not in a undocked project window.

and when i change the namen and dont press enter and click with doubleclick again in a new artboards name sometimes it does not change the name. really strange :/
