A Microsoft file hosting and synchronization service.
Is there a solution to this as I have the same exact problem with my personal O365 onedrive account, using the iOS OneDrive app.
Hi!
I'm not sure if this is helpful but what I did was to go to the WEB version of onedrive (onedrive.live.com) to see if my latest iphone photos were uploaded there.
They weren't, but instead they had some really old photos (2017 ones) that were still being uploaded. So I assume it got "stuck" somewhere in the system.
I then deleted a few (maybe 10-20 photos?) to see if it would help.
After a few hours, I noticed the words "setting things up" changed to "100+ photos uploading" and things were moving!
Not sure if this was a fix or just so happened to work, but you might want to try.
One problem though - A lot of my old 2017 photos are now listed as 19 January 2021, so I think the dates are a bit messed up. But my latest photos from this morning (21 January 2021) have been uploading instantly so it seems to be moving now.
Hope it works for you too! :)
