That is some nasty surprise… don’t think I would have bought it if this was the case to be honest.
Anyway, the Homey geofencing out of the box is terrible. There are alternatives which I tried (all of them, that applied to iOS) and the only one that works 100% of the time is Owntracks with a MQTT broker. I would suggest first looking into this prior to looking in flows that might or might not work.
