Where do I see bus detour routes

Checked the stm website -> my bus stop is not rerouted, so I walk to my stop -> there's a sign saying this stop has been rerouted, and to scan the qr code to see where the new route is -> I scan the code -> it takes me to the same map that shows my stop is here -> busses don't come, instead they go on sherbrooke which is not marked as a stop on the map?? 👍 hahaa what am I supposed to do. Where do I find the real map with the actual routes of the detoured busses? How am I supposed to know where my bus is??
