Peacock doesn't always work

I have been having so many problems trying to watch Peacock. I've replaced my DVR twice in the last couple months and for a few days, Peacock works on my main TV. When it won't work, I'll try going to the same show on a different TV in a different room and it always connects but the TV isn't in a room that's comfortable to watch. 4 days ago I swapped my DVR for a new one and Peacock worked fine until yesterday. The sound kept cutting out on a show I was watching. Later in the day, I tried to watch a different show and it wouldn't connect on my primary TV, but again it worked on my spare TV. Today I couldn't get a show I watched yesterday to connect. It looked like it was going to connect but the bottom half of my TV screen was just a mixture of colors and then went back to the list showing an episode of a show I wanted to watch. Once that happens, since it was happening all the time on 2 DVRs ago, I know it will never connect so I had to restart the DVR and then it worked. It seems the only way I can get Peacock to work is to reset my DVR every couple of days. This is not acceptable especially for what it cost to watch TV.
