OneDrive for MacOS [Big Sur] - problems uploading files following June & July 2022 OneDrive updates

Hi Folks,

I've been running OneDrive 22.131.0619.0001 on MacOs Big Sur 11.6.7 (20G630) on a MacBook Pro (Retina, 13-inch, Early 2015).

I've been having trouble uploading files to the OneDrive server from my Mac. The app sticks at "preparing to upload" for hours at a time. After 10-20 hours, the queue eventually clears.

This is not an issue of a large number of files or large files. Even with a few small files, they stick in the queue for hours on end.

I have followed the "Reset OneDrive" procedure and effectively re-installed OneDrive. I have uninstalled and reinstalled OneDrive. The problem remains.

This is new behaviour for me in the past month or so. The app was working well until recently.

I haven't installed any other new software. I haven't changed any network configuration. The hardware is still the same. I don't have any firewall or interfering anti-virus.

I raised the issue with Microsoft support last week. The suggestions from the agent were not very insightful. He promised to escalate the matter but I haven't heard back and he's stopped replying to my emails.

I contacted another Microsoft agent today. Eventually, he admitted to me that they “have had quite a handful of Mac users with the issue”. He wouldn’t or couldn’t give me any more information like how many other users are affected. He asked which version of MacOS I am using and would only say that it is "an issue of compatibility with OneDrive” and "some OS are more suitable and compatible than others”.

Has anyone else had this problem and been able to resolve it?
