Starting this morning, I found one local tv station unable to start due to tvapp-00206 on Roku. I’ve confirmed this happening on two Roku devices. No troubles streaming the same channel to either iPad or iPhone app.
Spot checking other Roku Xfinity channels look ok.
Roku version: 9.1.0 build 4919-46
Roku Model: 4660X - Roku Ultra
Xfinity Beta version: 3.6 | Sep 11,2019
Setting Xfinity Beta from “HD Preferred” to “All Available Formats” under Settings/Format makes no difference.
Station affected is WCSH TV6 on Brunswick, ME cable system.
