Help recover lost notes
So I have been using OneNote on my tablet for university notes for the past two years and never had any problems. However recently I had this issue where when I wanted to create a new page in one folder it wouldnt let me, the button was greyed out, but I could create pages in other folders. So I tried syncing the folder with cloud, that didnt work, I tried restarting my tablet, that also didnt work. I eventually tried logging out and back into my account. This is where the main issue began.
For some reason after I logged back in, only some of the notes were showing up, but the one folder where I couldnt make a new page was gone and with it all of my notes from this semester. I think that it probably didnt sync up with cloud, even though I tried multiple times and after logging back in it was just gone.
Is there a way I can access my notes that should still be in my device, but didnt sync up with cloud? I tried many things like getting it back with recovery apps, that didnt work. I also tried to turn on developer mode on my tablet and access the files that android normally blocks, but I still couldnt find my notes. Please help
