After clicking MyCard top-up in a mobile game, I can’t enter the MyCard top-up interface or a message of access denied appears?

If your phone is an Android system and the system has been upgraded to 6.0 or higher, please go to the phone setting to make the following adjustments. [Setting-Apps-(the apps you use now)-Permissions]. After allowing all the program acces permissions, restart the game to fix the problem and make the top-up interface appear normally.
