My Garmin approach R50 isn’t picking up club speed. Smash factor. Club path. Attack angle club face. Or face to path. It just shows dashes. It looks like on the device they are all set to on but still no reading?

All other metrics are working fine. 

I read that the device might need connecting to the garmin golf app by Bluetooth but I can’t find the device as an option on the app. It shows the R10 but not the R50

help much appreciated
