Thanks, @jtauber.com! Very interesting.

Some days my working day is: fix OneDrive sync issues. It has one job and it fails completely at that. All other cloud systems can sync things perfectly. Unbelievable.

That's often the case anyway! 😄

Have you tried using ChatGPT or similar? I tend to use LLMs only for things like this where the output is verifiable. If the problem has been encountered before many times it's quite reliable.
