Having serious issues with the Chromecast built-in on this Amp. Often the wi-fi network fails to show the device as an option to cast to. I frequently have to reset the wireless connection for it to appear. Even then, the Tidal app just keeps failing to connect. Same problem with phone (Samsung S9) and Tablet. Tidal casts to other wireless devices (Sonos speakers) without any problems.

Spotify works ok from my son's phone.... 

Anyone got any advice?
