For anyone with the new M1 MacBook Pros running Monterey, are you having problems creating a time machine backup? It seems completely broken.
The first backup seems to complete but then says “waiting to complete first back up” (this never changes). In the Time Machine preferences it also says “oldest backup: None” and “latest backup: None”. None of the files are accessible in finder either, even though space has been used up on the time machine disk. I even tried creating up backup in Safe Mode which led to the same thing.
There is a big thread about it over in the Monterey section, and its also being reported on the discussion boards at Apple, reddit, etc. I just thought I would flag it up here for everyone and see if others with the new M1 MBPs were experiencing the same thing.

Time machine experiencing multiple issues on Monterey (my personal issue resolved)
To clarify: I also have a 2019 MBP Intel i9 16". This one was upgraded to Monterey the day it was released and Time Machine works flawlessly on this one. The issue is with the 2021 M1 Max. The 2021's only OS option has been Monterey, This is the one with the issue. Set up as a fresh system
