App use issues

Why am I getting the error "Invalid invitation code. Please contact the inviter to regenerate" when adding a home member using an invitation code?

Can I voice-control devices in the App?

Why can't the device settings page or function page be opened, even if it is opened, the page is blank?

Do accounts registered in different countries/regions support device sharing or cross-region home member invitations?

Unable to create a device group?

How to create/dismiss device groups?

How do I share a device?

Why can't the mobile phone notification bar receive push notifications from the App?

How long can the device records (such as alarm records, door history of unlocking operations, power statistics, etc.) be kept?

Why is the IP address displayed in device information not the same as my home network IP address?
