Repeated notification 'Location Services Required' (but it is already given)

The location permission for Connect is given, but exactly every 24 hours I get a notification that pops up for two seconds and dismisses itself saying 'Location Services Required'; 'In order to retrieve weather for your Garmin devices, Garmin Connect needs locations services to be enabled.'.

It is, which I assume is why it dismiss itself, but then why do I get the notification in the first place?
