If you are the Admin, Normal User, or Temporary user invited by the Owner, you will need to switch the Address to the Shared Address.
3. If you have been invited to an Air-Mode lock, please enable the Ultraloq Air in the U-tec app, then pull the device list to refresh the device list.
4. Ask the Owner/Admin to check the App version number.
If the Admin uses the V1.0（v 01.xx.xx） version U-tec App, but you are using the V2.0(v2.x.xx.x) version, the inviting process will be failed. Please ask the Owner/Admin to upgrade the App version, then invite you again.
If you still cannot find it, ask the Owner/Admin to check if the user email they input when inviting you is correct.
