Restoring a previous version of a file

[Corrina321505675bhx]

So I've seen this question get answered before but all those solutions were for Windows and I'm on IOS/Mac. Basically I edited a file on my iPad, saved it to the cloud. My mom made some edits to the same file on her Mac laptop, went to save it and it asked if it wanted to replace the old version. Normally the way this should work is that both the old and new edits should be saved in the new version because the old ones were already saved and on the newly edited file right? But Adobe is incompetent and it undid all my previous edits and only kept the ones she did. Is there anyway to restore this on an Apple OS?

If you replace a file, you replace a file. Adobe did as it has been requested. The correct reaction to this would have been to save the second document under a new name.

You did save it to what cloud? iCloud? Document Cloud? A different cloud?

Ya I wanted it to replace the file with everything that was now in the
file. The version she edited had my edits so when saving that file and
replacing the old one all of that content should be in there. That's how it
works. When a video game overwrites your data with the latest save it
doesn't only include the last 10 minutes of play it includes the entire
play history. And the document cloud but when we try to look at version
history it doesn't show any. I just ended up redoing it unfortunately.

That's not the way it works but go ahead and blame Adobe anyway. Sounds like a problem with file management between you and your mom. 

Do you use Time Machine or a cloud backup?

[Corrina321505675bhx]

When a video game overwrites your data with the latest save does that save
now only contain the last 10 minutes of play? No it contains the entire
previous play history and everything you did since the last save. That's
how file saving and replacement works. In no world should a saved file
revert previously saved content unless you specifically asked it to.Adobe's
system goes against literally every other save system in existence.

Again, Acrobat doesn't do that type of saving--at least in my experience of 27 years of usage. I strongly suspect your mom edited a local version on the hard drive and it got uploaded and replaced the cloud version. Without more information, it's difficult to say exactly what happened. Perhaps the local files were not sync'ing properly with the cloud versions.
