I am making an app for iOS and added an auth in it. Trying to auth with a real phone number works perfectly fine (I enter a phone number in one view, gets thrown on enter code view and then sign-in), but when I try using test numbers, generated in Firebase, they do work like one time and then stops working for some reason (after being thrown on the enter code view, it immediately sends me back to enter phone number view). After some time they start to work again and I am able to use it one time. My guess is that I am being throttled every time and do get some kind of timeout. Can you please tell me if that’s the case or maybe there is some other rules of how to use test numbers I don’t know? Also my billing plan is Spark with no billing information provided.
Tried to use test numbers multiple times, works only once and then gets me into some kind of timeout.
