What bothers me is how and why does the system work if it takes an hour to notify if a sensor is dropped? I have removed mine to add air and the monitor went off within a minute or two. What the heck would cause it to wait up to an hour in some instances? This is very confusing, to say the least. But with the OP offering corroborating evidence of a problem, it certainly needs to be checked out.
In your example, your monitor never lost contact with your sensor.
When you removed your sensor from the tire, your monitor was still reading/communicating with the sensor. When the sensor was off the tire, you got an alert that the pressure had dropped. Your system worked as it should.
If/when our monitors actually lose contact with a sensor, that is apparently when the system goes into "looking for it" mode. During that 45 minutes to an hour span of time, the last reading the monitor received displays on the monitor and it looks like nothing has changed (temp-wise and with the pressure) and that everything is alright. But that might not be the case, as evidenced by the OP's incident.
It explains alot. Not sure that I like it. But it does explain it.
