content: Lost almost all my notes for the past many years. I really love the app but now it looks like basically all of my notebooks have been deleted spontaneously from OneDrive or wherever they are stored in the cloud. I still have the app on my Android phone but unable to get those to repopulate all that has been lost. Really a disaster and as I look online for a solution it seems that this is fairly common and no one from OneNote or Microsoft seems to offer any useful advice or even contrition
