We have seen that there are some problems with SMS.
1. Users in the US cannot receive SMS due to a problem with the sms provider.
2. The countdown while waiting for SMS is confusing as you can enter the code even after 10 seconds have passed. Some users then request a new code and when the different codes arrive the app gets confused.
3. After enrolling the SMS, the app hangs. We have found the problem.
All the questions will be resolved shortly. Thanks for your patience.
