do you plan to update the S50 Pro+ firmware to support the tidal connect funcionality?
The 4stream app is pretty much unusable. It works only as long as the app is open but still the delay is annoying.
The real problem starts when you reopen the app after a minute. It takes ages to update the current track on tidal or it alternatively goes to main menu.
Spotify connect works fine with little delay. I assume Tidal connect would also work so much better than the 4stream app.
The 4stream app is problematic, try the iEast or AudioCast apps instead!
