I wonder if rclone would have behaved any better than the web UI.
So you are completely stuck if you have too many files. Like I had. I used to keep pictures on onedrive, and used 6 user license. When the license expired, they locked me out completely. I couldn't download my own files! And the web UI is a crap.
So had to pay again for a year, this time I backed up all files locally.
This sounds completely insane, and I won't be using OneDrive for non-throwaway uses again until it's fixed.
(OneDrive is my Arq backup destination since I have no idea what else to put the storage towards, but now I'm considering my options.)
