I have an app that requirs users to verify their phone number. The app has mainly been used by people in Canada, until today. Now I'm getting a high number of reports from users in the USA that they are not receiving the verification code. I can see some users with area codes in the USA are receiving the code based on the fact my app shows their numbers are verified. However at least 2 of 3 new used with US area codes are showing as not verified. What am I missing?
I haven't tried anything yet. I would love some guidence.
