My 4K Apple TV with tvOS 14.3 beta freezes on Hulu, Netflix, streaming from my home movie library - everything. It freezes, stalls, gives me restart messages. I bought a new modem and a new mesh router system thinking that was the issue, but all the same apps, on my iPad in the same room as the Apple TV, run just fine. I’m beginning to think the problem is with the Apple TV itself, and not my network connection. Anyone else experiencing this?
