Same issue here!
Went for a drive before, tried to load Symfonium as usual and it says the beta has expired and I need to update, but there’s no update 
Was thinking of reverting back to stable, but I remember it being a pain to sign up to the beta in the past because it was always full.
Also, looking at the repsonses it seems switching to stable doesn’t restore settings properly, which would be a massive PITA
Got a long train journey tonight and was hoping to listen to my tunes from my Navidrome server, I guess I’ll have to use the Navidrome front end for now.
