I am not receiving notifications

Hello, I have 2 Wyze Video Doorbell V2 in two different and far away houses, but I don’t receive notifications from either of them when they come to visit me and ring the doorbell, I already checked if I have Wyze notifications activated on my iPhone, I also uninstalled the app and reinstalled it, the wifi signal is strong where they are installed, I thought it could be something on the part of the Wyze brand that they were working on, what could it be?
