What should you do if you can't add others to the home?

Dear user. If you do so:

Please confirm whether the user has the account of the App (Share devices and add home member must be processed in our App, not in the Alexa or Google Home App).
Please confirm whether you and the invitee are registered in the same country/region. You can only add users registered in the same country/region to your home. If the regions match but you still cannot add the member, you can refer to the relevant content.
If you use the invitation code to invite others to join your home, but the invitee's App displays that the invitation code has expired, and the invitation code does not exceed the validity period of 3 days, it means that the account of the invitee and you are not the same country / region.
If you are using a shared invitation code to invite others to join the home and you see the message "Invalid invitation code. Please contact the inviter to regenerate," it is because an invitation code can only be used to invite one user. Please ensure that the code has not been sent to multiple invitees. Once it has been used by another person, it cannot be used again to join the home. We recommend contacting the inviter to generate a new invitation code or adding members directly using the app account.
