I will have to disagree with you.
I have had no OTA updates in months on my particular phone. the wallet app was working fine last week, including tap and pay. My app updated, late morning (after i already used it to buy a coffee) and that afternoon tap and pay no longer works at the same location i used it 4 hours earlier. Additionally i tried it at 3 other consoles including vending machines where i work that always work.
There was no OTA in that time frame just an app update. Also i called Google Wallet support, and after 20 minutes of convincing them it was not my battery and case blocking the signal. She admitted it to be a widespread problem with other users. I simply want to know if there is a way to get the functionality back. The app itself no longer has any tap and pay options like it used to in the menus and setting.
