Hello. Trying to watch the Arsenal / City game via BT Sport app on iPad. Failing as video keeps freezing, leaving only sound available or worse, whole app locks up - no error messages. Reloading the app is required. There is nothing else running on the iPad. As we have Netflix & Amazon Prime, both of which stream perfectly over the Infinity connection, I don't think it's anything to do with internet speeds. This is therefore either an app or server capacity problem. Whatever, it's not good enough.
