We have 2 tivo boxes, 1 in the living room & 1 elsewhere. we had quite a few internet interruptions last thursday & since we can no longer access netflix via virgin tivo box in the living room. We can in the other room though. The telly we have is a smart tv & we can access it direct through there, so there is nothing wrong with the netflix account.
we have had another ongoing issue that we have put up with, the sound disappears on any one of the channels every so often, but it started at the start of covid & couldn't be bothered waiting/contacting virgin.. to fix it we just kept changing channels until it came back on.
