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