Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
This is a real problem because MS appears to be assuming their standard suggestions should work for everyone and WE ALL KNOW that's NOT the case.
MS needs to move on from that mindset and delve deeper into this anomaly. Their one-size-fits-all solutions are not working for everyone.
EDIT: I'm going to add that if MS wants my log files, I would be more than happy to send them to an MS tech for examination. I know there has to be some sort of clue in there as to the source of this issue. At least, I can see where the error is reported in those files.
