Ring 2 doorbell has a delay

I have the ring 2 doorbell, and it has had a delay from one someone is detected until it announces that someone is at the door. The UPS driver is back on his truck by the time I am notified that someone is at my door. I have had bell for at least 2 years so this is not a new problem but oine that is more noticebale with Covid lockdown.It also loses the live view and I have to reconnect. It loses the live with a minute, and takes several seconds to reconnect. signal strength is RSSI -47; firmware is uptodate; the network speeds are download 22,53 mbps;upload 31.5; and the ping is ms. I have a vpn on phone can this cause the problem?
