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.

I recently updated to AI v24.0 and just started getting this message. Very annoying.

Same here, running 24.0 on MacOS Majave. Even on the same file, I'll save and the alert comes up, then save again and it doesn't happen. Saving on Google Drive.

I keep getting "file has been modified outside of Illustrator" when I go to save (PC/Windows 10) AFTER I upgraded to 2020. This happens when I'm working from a server AND when I'm working off my laptop.

After updating to Illustrator 24.0, sometimes when saving a file, I get a popup that says 'this file has been modified outside illustrator. do you want to continue?'

This started happening yesterday or the day before maybe. It was after updating my CC apps to the latest 2020 release. I'm the only one accessing these files via Dropbox for business. Running macOS Catalina v10.15.1, iMac, 27 inch, late 2015)

But what do we do if we don't want to update to a cloud-based application such as Adobe Illustrator CC with the huge on-going expense that entails?

"This file has been modified outside Illustrator. Do you want to continue?" How do I make this go away. It just started randomly after I updated my CC illustrator for Mac yesterday.

Updated to CC2020 and Catalina V 10.15.1 and I am now getting this message all of a sudden.

I've had this happen, too, but I'm running ver CS5 on Windows 10. Watch out for changing the file name while the file is still open.

This is happening to us as of August 13 2019. Latest OSX release/updated, and CC/Illustrator 23.0.4. No iCloud saving. Files are saved/opened on a Windows Server 2016 file server. This JUST starting happening. No apparent changes whatsoever. Any ideas Adobe??

Also up to date - still happening.

I am up to date and it is still happening every time I save a file.

I had the exact same issue; I've always not used iCloud or DropBox on this particular Mac (10.13.6). I unchecked HandOff and made sure no files are linked to iCloud as Claudio Escobar but the pop-up persist. I then remove ICloud Device from Finder's Favorite then the pop-up goes away - not entirely sure why perhaps that has to do with the file system in 10.13.6.

I have the exact same issue as what Claudio Escobar mentioned below, must be a problem between Illustrator and iCloud backing up.

Problem persists on the latest build. Very annoying. Interesting observation from Claudio Escobar (June 9) below, maybe you should read it Abode?
