Flex box not working!

Greetings, @user_2dcf46! Thanks so much for taking a moment out of your busy day to leave a post on our community forum. I'm sorry to hear you're having issues with your Flex box, but you have definitely come to the right place for assistance.

We did receive notification a couple days ago that there was a known programming issue with some of our X1 and Flex devices, which caused them to display

an "Oops! Unfortunately this feature is not working" error. 

Fortunately, this issue was officially resolved on Wednesday morning (8/31) by our amazing support team, and a new update was sent to all active equipment. If you're still having this problem, please try restarting your TV Box by unplugging the power cord from the back of your device, wait 20 seconds, then plug the power cord back in. It may take several minutes for the experience to reload, but the error should go away. 

Please let me know if you have any questions or need assistance with anything else. Our amazing Digital Care Team is always ready to help, 24 hours a day, 7 days a week.

Hello, my flex box is still not working.  I've tried restarting it several times.   There is no error message.  The TV screen just goes dark after the welcome screen. 

nothing works with xfinity.  The internet is pathetic and the flex is just a joke. Been trying to get it working since many weeks but no luck.  Tried contacting customer service but there is no one who I can connect to and get some help.  Their customer service is a joke.

Xfinity's customer service is a big big joke!  They just message saying you are in queue and then nothing happens.  You try twitter, or try Facebook..absolutely no way to get any help from them!
