Why am I having constant problems with connecting Bluetooth? Everything else in my house works fine except for this scale. Also other users cannot connect when I am connected.

Hello!

Does your Wi-Fi network meet the requirements for the scale? What Are the Wi-Fi Requirements for an Index Smart Scale Series?

When you are trying to add a user, is that user going through the full pairing process? or simply accepting the invitation as shown in Adding or Removing Additional Users to an Index Smart Scale
