Xfinity stream

Every day I run into the same problem with Xfinity Streaming app. I have 2 brand new 2026 LG QNED 75B Series Mini LED 4K Smart webOS TVs and every day when I try to watch my shows via Xfinity Stream, I encounter the same issues. "This video cannot be played. We've run into a problem while streaming. (Error: TVAPP00148). Try again." I can keep trying and it will come on for a minute, a second, or a while... then it does this over and over and over all day. I have tried every solution posted online. Hard restarts, deleting/re-adding app, etc. and nothing changes. It's soooo frustrating. My connection is a very strong 5G connection.
