Doorbell Lag

I Have the Ring Doorbell (latest) running on battery. Over the last 6months the lag between someone pressing the doorbell and me getting the notification is ridiculous. By the time i get the notification the person has gone. This happens even if I am home. The Ring app has been removed and reinstalled Tried default setting Tried custom settings The camera has been rest Battery fully charged Tried varius locations for Wi-Fi hub There is no issue with Wi-Fi, its abot 3M between Wi-Fi hub and doorbell and has good quality signal. My mobile (S23 Ultra) has full signal and have no issues with any other app using Wi-Fi. No matter what I try, the lag persists making the doorbell useless, so much so that i am thinking of getting rid of all my Ring devices, and move to another make. My daughter has similar problems with her ring doorbell. What is going on ? Is it the app at fault All environmental changes have no impact. Thanks.
