I have a Samsung S9 phone and am trialing the docos on Magellan TV streaming service. I have two smart TVs a Sony and a Samsung, but when I press the cast icon it always casts to the Samsung TV not giving me any options.

My Sony is on the network and I can cast/link YouTube to it so its not a connectivity issue. Is Magellan just a rubbish app for not giving me the option lol?
