Had my first experience using it yesterday coming back from PUJ to YYZ. A notification was sent when my 2 bags were dropped off in PUJ. As expected there was no further information provided until I arrived back in YYZ.

A notification popped up for one of my bags noting it was arriving to the carrousel once back at YYZ and about 20 seconds later, the bag popped up on the conveyor. My second bag came about a minute later but there was no notification for the tracking of the 2nd bag.
