I have an 8MB .fla. Is that enormous or something? It auto-saves just fine, but when I hit "Save," sometimes it saves quickly and sometimes it creeeeeeps for a small eternity. Is it a known behavior? Is there something I should tick off in the Preferences? Thanks!
It should not take 20 minutes... or even 20 seconds! Are you saving to a remote location?
You should be able to set how often Adobe Animate saves in your preferences.
