Hi WangNi wang​,

Please check the Application logs. You will find Permission error in logs for the users which cannot see some parts. Provide those missing permission to resolve the issue.

I hope it helps.

Thanks,

You would have to set up visibility from the Thing/Template/service level depending on which parts needs to be hidden from certain users.

You may see this video that talks about available security levels:
