Hi there, @Author76! This could be related to wifi signal strength or interference between the router and Doorbell mounting area. The best way to confirm this is by checking your RSSI reading in the Device Health section of the Ring app. Check out our Community post about RSSI for tips on optimizing this signal. The most common culprits for wifi interference is distance, large appliances, solid or metal structures, and think exterior walls. As you mentioned these notifications not making it to your mobile device for some time, try removing and reinstalling the Ring app, as well as ensure there is no vpn enabled on your phone. I hope this helps!
