I suggest all of we SD TV users contact the live chat Peacock tech support so they become aware their recent app update is causing the problem. It worked until a few weeks ago. They changed something and they need to change it back. Here is the link to live Peacock support.

Every other app I have works perfectly fine on my 3910RW devices. Only Peacock has an issue.
If it is a Roku OS update issue, then they need to work with Peacock since only the Peacock app is effected. We all paid good money for their product and they need to stand behind it. These tech companies need to be made to stop hiding behind help bots, FAQ libraries, and user communities, and provide real customer service support for the products we buy from them. This nonsense is what will kill streaming TV in it's cradle. The average cable/satellite user will not stand for this random glitch from updates idiocy.
