I've had a Xiaomi projector with Android TV for a couple of months now and I just found out about live channels and how several apps make it work properly. I managed to install PVR live on my projector but there is no way for me to pay, the second I open the app I get transported to the live channels app and it asks me for credentials, which I don't have. Does anyone know if and how I can fix this?

(Forgive my ignorance on the topic, I'm new to this)
