Doorbell 3 - keeps losing WiFi connection

Hi all,  Hoping people can help with my Doorbell keeping losing WiFi connection.  Course of events is that I had BT broadband and had no issues at all.  However after recently moving to another broadband provider who use eero I've been having the WiFi drop on the doorbell. (I stress that the WiFi on other devices is working fine).  However a couple of weeks ago Ring released an update and there were no issues after that.  All of a sudden the Wifi is dropping again.  What I have noticed is that if it picks up movement then it will reconnect to the WiFi for a minute or two, though Live View never works.  I've just bought a new battery and it's fully charged.  If it helps, the RSSI is shown as 60 and running on 2.4 ghz Has anyone experienced similar and knows of a fix?  TIA
