Delayed notifications from doorbell and camera

So I have a Blink Outdoor 4 (NS36) and a Blink doorbell, and the thing that bugs me the most is that the alerts are delayed—sometimes 30 seconds, sometimes 2–3 minutes. The doorbell is slightly better, with semi-instant notifications (maybe a 10-second delay), but the outdoor camera is the worst. The majority of the time, I don’t get alerts from it for at least a minute after I trigger it. I have it mounted so that any movement in the area will trigger it, with a few privacy zones drawn, but they are on the sides of the area, not at all where I am walking. My phone is a Google Pixel 9a, and Google phones do not have specific battery optimization features, but “allow to run in background” is enabled on the app. The only other thing I can think of is that since these are wireless cameras, the Wi-Fi might be delayed, which would explain the delayed notifications. I am going to be installing a router today and hope that it has QoS so I can give the cameras priority. Has anyone else had similar issues? If so, what have you done to overcome this?
