Watch ESPN is now supported by Cox. Hooray! Since that's what I have, and until just recently I couldn't use the app, since they didn't support Cox. The problem I'm having now is that I'm stuck on a Comcast sign in screen. I can't get back to the original screen where you choose your cable provider.
I've uninstalled and reinstalled. I've cleared the cache and the data and force closed. I've moved it between internal and phone storage. The app will not start at any other screen than the Comcast sign in screen. It's amazing that the biggest companies (ESPN) make the crappiest and buggiest apps. Last time I checked I believe it had about a 2.5 star average because of lack of support, poor prformance, or other bugs.
