Issues with saving
2020 update often gives error while saving. It says the file cannot be saved. It then deletes the current file I'm working on, opens up a new window and I have to click save - as if I pressed "Save As..."
It happens quite often when I press "Cmd + S" to just save my artwork.
When i try to save, it shut down unfortunately
I'm experiencing this same issue. I'm saving to a network drive so that may have something to do with it. But i think it's an issue with the new "Background Save" going on, which doesn't seem to work because if you start doing something else within the document while it's saving it seems to generate this error as well.
I updated yesterday. Since then my Illustrator won’t save files, nor am I able to copy anything from Illustrator to Photoshop for example. I am working on a Mac with OS X Catalina.
