Thanks for letting us know of the issues you’ve ran into and sorry about the trouble.
When you say you can’t pull up anything new in TIDAL and new songs stop working, what new songs are you referring to? On what view are you seeing them? Could you please send us a screenshot of that view?
I tried the cache tip. It worked for 3 days, and now I’m back to the same state. I can play Tidal/Roon library songs…but anything new (Tidal playlist, Tidal genres, etc.) are all empty/don’t work.
