Missing Time Machine backups
I have a TM backup drive with the oldest bu being may-10-2021. I am running Catalina. a few weeks ago I upgraded from Catalina to Monterey and had problems so after much frustration I finally restored the Catalina backup. Now when I try to access files from before the upgrade no folders are shown. So if I'm in Documents and keep hitting the up arrow to go back in time it stops somewhere in February. The time line along the right side shows dates going all the way back but backups are only available to Feb 13. Are backups tied to system versions?
argh!
