The online banking of China Construction Bank keeps displaying "downloading the signature of China Construction Bank ...", but it keeps displaying when logging in. Please give me your advice.
There are three possibilities. 1 Maybe your computer downloaded a digital certificate before, and it is in conflict and stuck. Your computer is infected with a virus, and the virus is not cleaned up in time, which conflicts with the digital certificate. Have you ever handled the online business of CCB and given you a USB flash drive? You didn't insert a USB flash drive, so you can't download it.
