This is as far as I get. I was working fine as of yesterday on r16 with xposed but I decided to turn off the wallet plugin on xposed and start from scratch. All my recent transactions have loaded though.

I get that same message on my Note 2. Also I just upgraded my extra line to the HTC One and Google Wallet works perfect on that device. When Wallet stopped working earlier, I got scared and disabled it from the Wallet site. I did this because I wanted to go to a new rom and the Wallet app wouldn't open. I am wondering if this is the root of my problem.
