Video doorbell not notifying

I installed my Doorbell a few weeks back and for some reason I dont know if I hit a setting but now its not notifying me when someone comes into my yard. Twice now someone has come into the yard (luckily I knew about it both times.) but it never sends a msg saying theres a motion. One time it never even recorded the person dropping off a package at the house. I do live on a busy street so maybe that has something to do with it? Im out of ideas anyone have any help? It still notifies for me when a car drives by though.
