I wrote about this a few weeks a ago and today it happened again.Tried playing an album marked as high quality and atmos of course both not relevant.
Connect showed up as normal but selecting my player ddid nothing.
Going back into airplay and now i it worked fine.
Closing down Tidal in the app switcher and then connect plays as expected.
This is on ios 17.5 beta 1, but if this update has caused it I do not know.
Most likely this setup will work until whatever causes this problem to happen happens again.
