Do you meet all of the requirements for Fios TV on Xbox?
I am experiencing the same issue.
I have both FiOS Cable and Internet. I also have an active Xbox Live Gold membership.
My Xbox is conected wirelessly to the provided Verizon FiOS router yet when I try to use the FiOS App on the Xbox the system keeps telling me that I do not have a current subscription to those services.
I can't help with a solution, but I just wanted to say I'm having the same issue. Error message says I don't have Version/FIOS TV or internet service (Triple Play bundle) when I do. XBOX works great with all the other apps... Very frustrating.
I called Verizon / FIOS Tech support today and spoke to two different Rep's and neither could help nor did they really want to help me out which is sad on Verizon's part.... They both read from a script and stated it's not Verizon's problem, but the writer of the app. Both wanted to pass me along to their "Expert Care" group which you have to pay for. I declined.
I am also having the same issue an i have the triple pack and the best tv package. I used to get them all before the update but now some channels will work, some wont work an other times then the message will just pop up. Very frustrating and Verizon needs to be made fully aware an put out a patch soon.
