Why can't I log in to the mobile cloud attendance system?

1.

Cell phone problem. The running memory of the mobile phone is relatively small, so it is impossible to log in.

2.

Network problems. If the network is unstable and you can't log in to the cloud attendance, you can log in to a slightly empty place.

3.

Turn on the flight mode for 5 seconds, then turn it off, and log in after waiting for the network update.
