Samsung TV app not working

Have you made sure your model is compatible with Xfinity streaming app? https://www.xfinity.com/support/articles/activating-xfinity-stream-smarttvs  

if it is, you can always reach out to Xfinity support for them to refresh your account on the backend

That may help give you a better streaming connection

I have the same problem.  The app won't load.  It just has the Xfinity splash screen with the 3 dots moving back and forth.  

I have been in contact with support and they ran out of ideas. They sent out a technician this past Sunday and all the hardware is in good working order.  He measured 1.23gb download speed...

I tried all the troubleshooting steps on the website.  As I mentioned the issue started happening a month ago, so yeah, it was working on my compatible TV before.  For about a year, actually the Samsung TV version of the Xfinity app worked nicely. 

Whatever they did to the app recently [Edited: "Language"] it up.  It won't even load now...

Quick update...  The app loaded last night.  I could watch Live TV and Recorded programs, but now we are back to the original problems.  

1. "Attempting to Reconnect" while watching any channel.  I can watch Live TV, but about 1x each hour, the stream will freeze for like 30 seconds, then the screen goes black with a message saying "Attempting to Reconnect" will display.  About 30 seconds later, it reconnects.  
2. Fast-forward through a commercial skips back to the previous commercial.  Funny, right?  While watching recorded programs, I want to fast-forward through a commercial (awesome perk, BTW, when it works).  I hit the fast-forward button, and several things happen.  Most of the time, the stream will jump back to the previous commercial.  Sometimes it secretly fast-forwards at 1x.  I say "secretly" because the progress bar for the show does not come up.  So the screen is frozen and you think that nothing is happening, oh, but it is...  syke!  Sometimes it will just pause.  If I hit pause first (the middle of the circle on the remote), I can often get it to behave.  

These problems don't make the app completely unwatchable.  But super annoying, and imagine trying to explain it to someone else...

FYI...  and this is important, I have been in contact with Xfinity support.  I followed both sets of instructions from support above.  So yes, my TV is plugged in.  Yes, the model of the TV newer than 2019 and is compatible with the app.  Let's see what other "idiot-test" questions have I already passed?  Oh, yes, a technician has already been to the house, and the internet is working at top-notch speeds.  I have tried Xfinity stream on our Amazon Fire TV, and it works fine.  We can also watch streams and recorded programs on our smartphones and iPad. 

THE PROBLEM IS WITH THE SAMSUNG TV APP.  Just wrote that big so readers see it...  Thank you 

Well, either the account reset or the cache clearing has the Xfinity App not loading again.  It's back to the Xfinity Stream splash screen with the 3 rotating dots...  Bummer... 

Just updating here for anyone following.  The issue with Xfinity App not starting up was solved by tech support resetting the app on our account.  We had to log in to the app again and it loaded.  The fast-forward while watching a recorded program still remains.  It's the least annoying issue...
