Delay in motion notifications, multiple cameras

For several months I have been experiencing motion notification delays on all my cameras. Sometimes it takes almost two minutes before I get notified of a motion event any time of day. I have (2) Spotlight battery cameras, (2) Ring floodlight cameras and one Spotlight wired camera. All my cameras report healthy with good RSSI values. I also have additional Xfinity wireless pods in multiple locations throughout the house to ensure a consistent WiFi network coverage to include well beyond where the cameras are located. I use Comcast for my ISP and average 500mb down with 20 - 25 mb upload speeds. Have reset and rebooted everything but can not resolve the delay issue. I would appreciate any suggestions. Thanks.
