FWIW, I contacted TIDAL support and was told I had reached 9,999 “items” (I presume they mean albums) and that that is the limit. Insane. Anyway… Thx for the followup. I have more than this count of albums on Qobuz.
I was considering moving to TIDAL only now that MQA is over, but this one fact is a no-go for me. I will keep TIDAL because some albums are not on Qobuz, but it’s clear this is not an option.
