I cannot join a group. How do I solve this?
1> Check whether your data network is working normally.
2> Exit and reenter the interface for joining a group, re-enter the same 6-digit channel number, and join the group to use the intercom function.
3> If the problem persists, quit your account, log in again, and try again to join the group.
4> If the problem persists, you can also restart the app, and try again to join the group.
