What if the parents in the knowledge tree haven't logged in yet? Is there any way to send an invitation message?

Hello, very much. Happy. Because. You replied that this may be caused by the peak of internet access. You can try logging in at another time. You have disabled the network function of the software you downloaded by using the network blocking function of other third-edition software. You can try clicking on the software that prohibits surfing the Internet. There is a network switch there. Open it! Maybe you can try to shut down and restart, or you can force the software to stop. The specific stop method is similar. Click Application Management, download the application, find the application of the knowledge tree, and click Forced Stop on the left. You may be asked if you are sure here. Just press OK.
