Same issue here!
Get the warning when working on a file from a server/network file AND from files living on desktop.

No update yet... :-(

I'm getting this message too! So annoying!

I have now reinstalled Illustrator and installed the prerelease. No change. Still get this message. And the saving of files still take forever..

Thanks Anjali, but this has not been fixed at all. I don't see a 24.0.1 update - has it not been released yet?

I'm not seeing a 24.0.1 in the updates in CC App

How is this an issue again (or, still)?

Same here. Only appeared since updating to 2020 yesterday. Running Catalina, but the only thing that has changed prior to the errors appearing is the new Illustrator update.

This bug was fixed with the release of version 22.1 (see previous bug report: http://bit.ly/2XDoBhv) but has crept back in with version 24.0.

Please accept my sincere apology for the inconvenience and disappointment the issue has caused. We have a fix available in the pre-release build. Please visit https://adobe.ly/1o2SDsg and get the latest build for version 24.0.1 and let us know if the issue is fixed for you or not?

While the build is pre-release, this build is of production quality. Please feel free to use / recommend it for your day to day activity.

Thanks

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.
