OneDrive stopped working for me on macOS and iOS.
Just like everyone else in this thread, I cannot get OneDrive to load my Business account on macOS.
On iOS it isn't updating folder contents correctly. I could have four folders, and the iOS OneDrive only shows two. I can force-kill the app and re-open it over and over, and it makes no difference.
We pay for Office 365 at work, and I use OneDrive quite a bit. Documents are synced and signed by me on my iPad with the Apple Pencil, then synced back to my Mac where I then submit them. I may go days at a time where OneDrive is the only Microsoft app I use.
And now it's broken on every platform I use it on. It won't load at all on macOS, and it is still not updating folder contents on iOS. What the hell, Microsoft? This is how you treat business customers?
