This is still an issue as of 3/26/2021 on OneDrive version 12.20.
But I really need to back up my iPad because storage is getting low.
This wouldn't be as much of a problem for me if I could just plug my iPad into my computer and transfer files, but that requires iTunes (a music and video streaming app?), and when I tried that, iTunes swiss-cheesed my system and dragged it to a halt, and the only option was to reinstall Windows. Now the computer runs great! And there's no way I'm installing Apple bloatware again.
Please, Microsoft, talk to Apple about making a Windows app for wired iPad file transfer that won't break our systems, especially when you're going to halt backup via OneDrive indefinitely.
