This is more than a big issue. And seemingly simple to correct. It seems to me that, should the app EVER lose communication with the device after it’s been started, an alert message should be sent to the Administrator. So, basically, the whole system can be circumvented. Which means, without the honor system, the whole thing is worthless. Which means the whole thing is worthless.
This is common sense.
This should have been corrected years ago.
As I said, it’s an easy fix. So maybe they will fix it.
