I have Xfinity and when trying to use Pandora an activation code came up and asked me to enter it in the mobile app to activate my device. I did that and on my mobile screen it said activation successful, however on the tv, the screen did not change and activate - and actually did the opposite and music stopped playing, so i logged out of my mobile device (thinking it might be a problem with having both open at the same time) but that did not help either. I then attempted to login using email - entered my info and it said that no user existed under that account (however I logged in online without any issue) I triple checked that I was using a proper email and password with no typos all was correct. Again, I had no problem logging in through my mobile or through the web, just on the xfinity platform. I then worked around by creating a new account under a different email. It worked and let me create account and listen, but then 1 minute later said that someone else was listening on my account and you can only listen on 1 device at a time - this was a new account that I just created through the xfinity platform, so there was no was I was logged in in 2 places. Obviously some kind of bug going on with this app.
