Audio/video out of sync on xfinity stream using roku

There was an Xfinity app update the other day. The app is now V6.13 build 0. I was hopeful but started again. The live news channels are horrible. I like msnbc but can't tolerate constantly backing out of program to get audio/video back in sync. Seems to happen more after a stupid commercial. Though yesterday while watching morning Joe while Mika was talking it happened. The audio was in FF like it was trying in catch up. The problem is the audio starts before the mouth moves. It Happens after commercials and if there is a little glitch in the video. Say a sec or so. I can get MSNBC through NBC without problems, but I can't tolerate the same 3 commercials that play 4x in a row. Stupid! I can watch morning Joe through peacock without a problem but that's the only program that they want to give us live. I don't know if its Xfinity app or modem but I'm tired of it. I just went back to cable, but the boxes are so slow, rebuilt. One wouldn't turn on so we returned it for another and the second one act like it wasn't going let me load my apps like max, etc. All my other apps work on Roku Its just Xfinity. They should have left it beta version. At least it worked. My husband wants to look else well. Praying for a new broad band co. in our area so we can finally be done with comcast. Yes, loyal since 1985 for what reason I don't know. But looking around.

Xfinity stream app has video/audio issues on Roku. I Have taken numerous modems back and exchanged thinking that is the problem, because they get so hot, I could fry an egg. Because of my numerous visits to the store A Comcast tech came to my house yesterday. He was very nice and changed the end to cable going into modem. Took out a booster that a comcast tech put in a few yrs ago. Did something at cable box outside. All good till this morning. The audio and video have been out of sync since this morning. I am paying 192$ for cable and internet. I'm so tired of this mess. My Roku tv I purchased in 2017 streamed cable through the streaming app without problems. We Drop cable in January but decided to go back about 3 weeks ago or more and nothing but problems. I'm constantly backing out of MSNBC and going back to program to fix it but just goes right back. All day I have been watching audio ahead of video. If it isn't fixed by Monday, I'm getting rid of cable and going to try and look for different internet service. Tired of posting on Roku and Xfinity. The Xfinity app don't work on any of my TV's or Roku 4K+.
