I'm using Adobe Animate 2020, last night I was working on something and saved it, then closed the program and went to sleep. I know I saved it, because no "save changes?" pop-up came up when closing it. This morning, when I opened Animate I checked my recent files, and it was there but was completely reverted back to when I first started the project. There are no autosaves for it either. I don't know what happened? Help would be greatly appreciated.
there's no way for a file to revert to a another version or an earlier save.
it's possible you're looking at a previously saved file and you have no other saves or you do have other saves. to check for other saves, before doing anything else use file>save as to see the last directory where animate saved a file. then check that directory with a file browser.
