I was attempting to redeem the free 25gb of Google Drive that HTC One owners get with the Sense 5.5 upate.. Didnt have the redeem option when I launched the app on my device. Called HTC customer service 1 (866) 449-8358. They sent a link for it and now I've got the addtional space.What was the issue and how did you fix it?
It might help someone else.
