Geofencing Issues

Hi All,
I have had a Eufycam Plus set up for a few months now, and am having issues with Geofencing that seem to be getting worse and worse. I am running Homebase 2, and have Geofencing set up on two Samsung Galaxy S21s.
Geofencing now takes a long time (5 or 10min) after entering ‘home’ to register, and this morning has switched from ‘home’ to ‘away’ 3 or 4 times without me leaving my desk.
Anyone got any suggestions?
