First, the network of the trial version itself is unstable, and disconnection is normal. If you use China Telecom in the South, the software is the default. Add a network address Netcom in the north: 61.155.136.9.

Second, the trial version itself is for customers to learn about the software. Since the company sends the user password to customers, it just wants them to understand it personally, and it will definitely not stop it for customers.

Third, a trial number can only be used by one person. As long as your mobile phone number and verification code are not visible to others, no one will log in to the number. If the software prompts you to log in elsewhere and is forced to log out, it must be because you accidentally opened the software twice. Just turn one off.

Whether it is the official version or the trial version, you cannot log in at the same time.
