LR6 Unable to Sign Out after Big Sur Upgrade

I'm unhappy because I had something that was working perfectly well, and now it isn't.  Because I apparently on a land mine.  By your logic, it's my fault I stepped on a land mine I couln't see.  Furthermore, when I bought LR6 back in 2015, how was I to know my photos and their metadata would soon be trapped in a subscription model I never wanted or agreed to?

I'm not going to pay a subscription for something I use once or twice a year.  I happily paid for upgrades over the years from LR1 to LR4 to LR6.  But now Adobe wants to install a permanent leech on my wallet, whether I use it or not.  No thanks.  There are other optoins, and I plan to try them.  Adobe is giving other software makers strong incentive to build great alternatives.

Agreed.  That's one big reason I'm switching to Windows.  Between the Big Sur BS breaking apps, and making my mac more and more like an iPad, and the forced march to Apple Silicon, I think I'm done with Apple. Have you tried deleting a message thread in the Big Sur Messages app?  Lotsa clicking.  Keyboard shortcuts no longer work.  Like the app was never designed for a keyboard.  Thanks for that Apple.

I should have "Signed Out" of LR6 before I upgraded to Big Sur.  Hindsight is 2020.  I could restore from a Time Machine backup, but man, that's a PITA.  I'll try Adobe support first.

Unfortunately, the "Account management screen" offers nothing for me, since I am not a CC subscriber.  I have LR6.  If there's a secret screen somewhere on Adobe.com which let's LR6 owners disassociate a license from a computer, I haven't found it yet.  And doing through the app does not work on Big Sur.
