Problems with new OneDrive cloud sync feature firmware 3.3.2

I put by Work credentials in for OneNote and while it accepted them and I logged in correctly, when I viewed the files there was an error and nothing was shown.

Then I switched to OneDrive personal, and I was able to browse all my files and open PDFs and edit them. That's really, really cool! However, it had problems saving and uploading the changes, it would say it was merging the annotations and uploading them, but the screen just stayed on that until my Note Air 2 tablet went to sleep. No changes were uploaded, even when manually pressing the Cloud icon on the NeoReader toolbar. I understand other formats are not supported yet, but I thought PDFs were and I couldn't get it to work.

Additionally, directories that I had previously accessed and opened files with, with unsynced changes, would disappear from the folder/file list so I couldn't go back there.
