How to check the performance of apiKey for Yandex Mapkit (Android)?

Question

Android

Hello!
Yesterday they sent me a key for Yandex Mapkit^

You now have a valid Key #1 (...) for the Yandex.Maps API (paid version).

But when I inserted this key into my project in MapView, absolutely nothing changed - Yandex.Maps tiles were not loaded, and are not loaded (attached a screenshot).
Is this a problem of Yandex Mapkit or apiKey? Is it possible to check this key somewhere at the time of work? What could possibly be the problem?

Answer 1

Didn't use Yandex Mapkit, but there are a couple of general considerations:
1) Forgot android.permission.INTERNET ?
2) You need to look in logcat , there may well be a clue.

Answer 2

In my case, it helped to contact Yandex support, activated the key on my side and everything took off
