OK i just observed this a couple just recently. When i open OneDrive using the Apps library in browser i am now getting redirected to https://www.office.com/launch/onedrive?auth=2 and it's not loading my onedrive anymore and i am getting the Getting your files set up on OneDrive is taking longer than expected. I tried the following:
* Log-off / Log-in
* Use Edge
both to no avail. I was able to access the page that i am looking for using the OneDrive for Business app and got redirected to our company URL. Question now though is why is this happening? I also have a powerautomate rule that was running smoothly for a couple of months now until just recently and it looks like my backups are not being saved in OneDrive even though the powerautomate had been running successfully.
