It means that a router can only be bound by one account if it has been bound by another account. If you need to use another account to control it, you can try the function of sharing the router (this prompt will appear when you use the second mobile phone to bind it). There is also a possibility that the router you bought was used by someone else!Solution: Restore the router to factory settings.
It is now supported. You can select a binding account when you go in for the first time.You can also click the upper right corner later, and then click "Log out" to re bind to another account.Give it a score:)
