Google billing Internal Test : Test Card not showing

Question

I have my app in the internal testing track but when Testing, the test card did not show up and it asked for the real credit card on both real and virtual devices.

I have tried some method recommended by StaclkOverFlow such as removing all GG account and clear Google Play data then add only one tester account but I have got no luck.

Could you please give me some reasons why test card did not show up???

This is the picture when testing:

Answer 1

My mistake is not adding License Tester. After adding, clear Play Store Data and re-login by License Tester account, test card showed.

Answer 2

I spent 2 days on it until I found out that after adding license testers I also needed to check the checkbox next to the added list in Setup -> License testing.

The checked checkbox on the testing track page is not enough.

Answer 3

Clearing play store data in app info resolves my problem.

Answer 4

Just had the same problem. Eventually it will show up, but to speed up the process, go to "Google Play" app's settings and in Storage, tap "Clear data" (not only cache). Then test cards will show up immediately upon re-launching your app.
