Even when I’m watching on just the phone or Mac, it’s buffering. There definitely seems to be that casting issue though when I do get a good few minutes too. Apple TV doesn’t like RTV cast from mac or iPhone. I tried the app to cast today and it went on there, sweet as you like. Then a minute later, it buffered again
It doesn’t matter if I’m on WiFi or 4G either. It is a complete mystery. There’s not much that I haven’t explored in terms of my own system. That’s why I was going to try changing VPN. The one thing I’m a bit suspicious of is the actual internet. 4G does work that bit better than BB. But everything else is great. Netflix, Aussie TV.
