MeTV on Xfinity Stream app

We normally watch MeTV on the Xfinity app on channels 942 and 1180. We do not utilize a set-top-box (STB) but stream the channel. Yesterday, July 24, 2021, for at least the third time this month we could not view MeTV. I have 3 Samsung Smart TVs and several other devices that all have the same issue.

When this occurred we lost the channels for the whole day. We get error code TVAPP-00281. A handful of channels did not came in, e.g. LAFF. 

Last week a tier 2 agent said he learned from a tier 3 agent that this was a known issue at Comcast.

1. The support automated message says to unplug your device. Which device? We have no STB.
2. Agents suggest uninstalling and reinstalling the Xfinity app. Why?
3. Why not make all support aware when there is an outage like this one?
4. Could you let support know that there are users than stream Xfinity without a STB?
