Anybody else experiencing issues with iOS 8.1 Beta 1 and T-Mobile Wi-Fi calling not working? It worked flawlessly on the iOS 8 betas, iOS 8.0, and 8.0.2-- but ever since updating to iOS 8.1 beta 1, I'm not getting "T-Mobile Wi-Fi". Just "T-Mobile," and it's using the regular network to send SMS and do calls. Note: I thought it may have been due to SMS Forwarding being enabled, but I went ahead and disabled that and even restored my device as new, and Wi-Fi calling functionality is still not back. Odd thing is, if I go to Settings > FaceTime and try to turn on iPhone Cellular Calls, it does warn me that Wi-Fi calling is enabled and that it will be disabled if I turn on the cellular calls.
