What should I do if the excellent elephant products are delayed and only the bank card is displayed?

Network signal difference. The delay in the certification of elephant premium products can only show that the bank card is caused by poor network signal. Software is a platform that needs network conditions very much. When the network is not good, it will lead to the failure of platform connection, unable to authenticate information and unable to log in. You can replace it with an excellent network. Bank card refers to a credit payment tool issued by commercial banks (including postal financial institutions) with all or part of the functions of consumer credit, transfer settlement, cash deposit and withdrawal, etc.
