Hi, I don’t know if your issue was resolved. I had the same exact issue and 2 whole wasted days online chat. No one could figure it out. I searched online, Reddit and here. I was determined to figure it out myself if they couldn’t. Something told me to check what email address I used to create my Verizon account. I never verified it and it was different than my Google and YouTube which are the same. I changed it. Logged back into Verizon and went the usual steps to see if this time I could activate…darn if it didn’t work!!! If you haven’t see if that may be the issue. Although by this point you may have already opted to sign up on YouTube TV directly or figured it out. But this is also for anyone who may be having the same issue and finds this post.
