Mine is the other way round. Prime works but Netflix says subscribe. BBC iPlayer (I'm in the UK) takes me to the app store.
In all honesty I don't think this is ready to be used. Too many little issues when its side loaded
Off topic but did anyone outside US managed to get the launcher recommendations to work perfectly?
I had this issue with the HBO Max app. I had to go to the bottom of the For You page and into the Get Better Recommendations section and activate it under Other Services.
Mine is worse, i check all my services and they deselect automatically, for you is not available for me either. All i get is Home Apps Library ðŸ˜
edit: I do have the Chromecast with Google Tv tho.
I don't know if this is helpful but if you use the Google website to search for "Friends TV" in the right hand panel there is a section for "Watch now", below that is "All watch options" click that and then you will see an "Edit Services" link that you can select your services. I think this will updated your "Subscribed" services for the account you are logged in with.
I mean you can't really expect it to work properly outside of the Chromecast, that's normal, it wasn't meant to be sideloaded.
