I have HTC 10 which I received 2 days ago. I have completed setup of the device and signed in to my google account.
When I go to settings>backup & reset, there should usually be an email address to which backup is associated with, but it is grayed out.
I read on XDA forums that other users also had this item grayed out. HTC Help app reports that there should be an account, under that setting. I have other phones which do have my gmail account there. Any one has similar issue?
I just wanted to step in and see if you had found a solution? If not, we'll be happy to dig around and see what we can find!
I didn't find solution for this. I returned T-Mobile variant of the phone and purchased an unlocked HTC 10 from htc.com and there were no backup issues.
