I used to have a chromecast where the app worked perfectly. Today j bought a new tv and i am unable to set the app up. I used the same account as i used for years, i even made a new account because i saw a suggestion for that. Is there a way to make it work? I have a philips tv from 2023. If i use the account on my laptop it works fine. If i use it on my iphone it also gives me the error message: video not supported.

I have version theater v1.11.1 and the platform is titan2.5.
