Geofencing issue

Options
Hi,

my wife’s iPhone 7 location is sometimes not recognized, altough she’s almost everyday at home. iOS and tado application is up-to-date, suggested location, background app refresh and cellular data settings are set. Home wi-fi recognition is not turned on. Auto-assist enabled. Anyone have similar issues? Is tado aware of this issue?
It would be a nice and helpful feature to be able to manually control Home/Away.

Thank you
