Yes, I have the same issue as well as no volume control etc...
If Tidal/Qobuz icons disappear from the app, please go into the app, logout and disable Tidal/Qobuz, then enable it and re-login.
If it still does not work, power cycle the Lumin.
If it still does not work, please uninstall the app and reinstall it again, and re-do the login(s).
If Volume Control does not work, please go into Settings -> Options under LUMIN -> turn Volume Control Off then On.
If all the above have been done and it still fails, please perform a reset as follows (note that the current playlist stored in the Lumin instead of the app will be cleared, and all settings will be reset):
- Power off the Lumin via the Lumin power supply button (not the app).
- Disconnect all USB devices from Lumin, if any.
- Find something to press and hold the reset button at the back of Lumin.
- While still holding the reset button, power on the Lumin and keep holding the reset button until the front panel shows some small text about factory reset. Then you can release the reset button.
- After the Lumin is booted up, re-login Tidal/Qobuz.
