Xfinity Streaming timing out with the same 281 error code

This app really needs some attention.  Comcast/Xfinity have been in the business for many years and have had almost a monopoly on the cable market.   They do internet, but I am disappointed in the streaming app.  There are many design issues that should be addressed but first make a stable product.  Every few days it just stops streaming for no reason, it buffers then stops.  Being versed in high technology, I do the normal steps to troubleshoot.   Such as checking internet connection, I can stream every TV app I try, Tubi, Fawsome, Prime, Hulu, Paramount+, Peacock and so forth with no problems whatsoever.  Once again, I go back to making a app that is stable and reliable.

1. Restart TV

2.  Check for any updates on TV (my Samsung TV has the latest updates and has had off and on issues maybe a couple times a month and I was able to self-resolve by following some the steps mentioned)

3.  Uninstall the app and reinstall (hoping this would clear any cache that may be causing the issue.)

NOTE:  The app starts most of the time however when trying to stream it times out with the error code.  This latest round of failure happened the day that they were "fixing problems/ upgrading in our area".   I was without service from 7am to 6pm (essentially, I would get a message every couple hours saying it was back, and I would use the internet and then it would go away again).  Then other times the app goes into perma loading.

After trying to get through the Xfinity Assistant, which is very subpar.  Today we have AI that can gather all the resources that the technical department and present multiple options.   Work through the Xfinity Assistant for Xfinity streaming and there are only a couple options (that are completely useless).  Now try calling, what a experience.  There is no option for Xfinity Streaming, so you try to select others to no avail.  Finally, after pressing 0 multiple times and saying representative I got a human.  Now the human has to verify my account and get information for 5 minutes.  Next let's troubleshoot your connection for 10 minutes (even though it was explained several times all other streaming apps and browsing the network works).  I explain it's not the internet it's the streaming app.  The 20 minutes more of waiting for them to check "on their end".  Then they say they have run through the troubling shooting steps and so no problems.  What am I supposed to do?  Have no streaming that I pay for?  Now I am waiting to get a text within an hour, for further steps.  What is the text link to?  Installing the Xfinity app (not streaming app).  It happened before and I was able to delete the streaming app and restart, and it seemed to work.  This time it continues to fail. 

If the app becomes more stable.  Then there should be some serious design conversations to make this the premier streaming app.  I would include the ability to punch in a number to get to a specific channel.  It will be challenging but from the user standpoint we would like to select a channel without having to scroll several hundred channels to get there.  Think about that as a user experience.   I worked in software development for 11 years and I am familiar with useability testing.

Essentially there are a couple issues happening at this point.  Sometimes the Xfinity Streaming App starts and loads the menus and when I select watch on any channel, it will bring up the meta-data for the channel but then will fail on loading the video.  Secondly, sometimes when starting the Streaming App, it just never finishes loading.  

Is there a direct number I can call to get this resolved?
