What should I do if the system prompts that "the ciphertext generated by CA authentication cannot be empty" when China Bank's new enterprise mobile banking signs a silver tax loan?

How to deal with the system prompt that "the ciphertext generated by CA authentication cannot be empty" when China Bank's new enterprise mobile banking signs a bank tax loan;

This prompt may appear because the authentication method you selected is SMS. Please try to use the authentication method of dynamic password+SMS verification code or mobile phone shield+SMS verification code. It may also be because the mobile banking version is not the latest version. Please complete the version update before trying to sign the contract.
