Hey there! @Ankan, I completely understand your frustration with Mobile Presence not displaying the correct status.
AlecM is correct in suggesting to check your permissions on the Iphone 7 to ensure that ST is “Getting the location from that phone” is turned on.
Here is a troubleshooting article on setting up mobile presence: Use your phone as a mobile presence device
To Reset Mobile Presence, You simply toggle the option in the ST Settings to get the location from your phone to off and then back On.
If the symptom persists after a reset, I would recommend creating a Support ticket so we can look into your concerns further.
You can reach out directly to a support team in your area using the below information:

I hope this message finds you well!
