OneNote, I trusted you. But you failed me. You failed me once when I accidentally surpassed the storage limit, creating a mess and making me pay to temporarily lift the storage size. I had to manually recover the notes from an older OneNote version because the newer ones don't have an "export to PDF" or even to proprietary OneNote format. I decided to give you a second opportunity.
But you disappointed me again when I tried to move note sections to a different notebook from my iPad. Then, your app crashed and my notes were left in an inconsistent state. Some notes appeared on the new notebook, but others showed as "not synchronised yet", and every time I tried to open the iPad app again, it crashed within seconds. So you lost my university notes.
I'm going back to regular file sync. Hello @nextcloud, good bye Microsoft.
