Items in my sidebar disappear after a few days
I regularly put folders in my sidebar because I frequently use them. Yet most of these items disappear from the sidebar after a few days. And then I have to go through my whole folder-structure in the Finder to get where I want to be. The sidebar used to be stable: what I put there would be there until I removed it. What happened to this? Why does Apple no longer support this crucial feature? How can I restore it. I am currently using Monterey, 12.1, but the bug (as I see it) also occurred in the previous system. I am on a MacBook Pro 13', with M1 (but it also occurred since a year on my previous MacBook Pro).
Can someone please help. Is there perhaps a Unix way to deal with it on the Terminal?
