(Starting a new thread because the previous one involved several different behaviors.)
I still get the behavior where I locate an album in Tidal, click Add to Library, it gets added and then after a second or so is deleted again (and the UX shows “this album has been deleted”). I described it in more detail before: go into the album shows 12 tracks, then 0 tracks, and gone.
Specifically, I wanted to a few Doors albums I don’t have (after reading Michael Lavorgna’s enthusiastic description of MQA on Bluesound); I could add Morrison Hotel and L.A. Woman without problems, but Waiting for the Sun.
The server is build 94 (64 bit) on Windows.
Same behavior with a Windows remote, build 94 (32 bit), and an iOS remote, build 88.
