My problem is long to read, but elementary:
Introduction, not the actual problem: suppose we have a downloaded file in internal storage "file.pdf", we open it with Adobe Acrobat Reader. We edit the file, for example by adding annotations. Now in order to save it (to the same location in internal storage where it was when opening, as opposed to saving to Google drive or adobe document cloud) we just close it and it says "saved" in grey text, and indeed that works, the edits are saved, replacing the old file there is the new one.
Now the problem: I'm actually trying to do that, except with a file in google drive. That is, I open google drive, I look for my file2.pdf, then I choose "open with" adobe acrobat reader. I edit the file. Now when I want to save it, there are two options that don't work:
-If I just close like before, indeed it says "saved" but, it doesn't save! Changes are lost. Why this happens?
-If I choose "share" and then choose share to my own google drive, instead of saving it creates a new version and puts it in the root google drive folder. Then I have two files, the old one and the last edited one, and this is very messy. I would want instead to save in the same place and replace the old file with the new one edited.
Important note: This procedure works FINE (without the problems described) in my PC (windows 10) using the analogous programs, that is Google drive for desktop and adobe acrobat reader DC. That is to say I open pdf from the google drive folder in windows, edit them, save, and the changes are saved.
