Added two AskForPermission doesn't work but, the aia code @d_Taraoa posted works. So I attached some steps from this code to mine then GPS went to be as normal.
- AskForPermission moved to Clock from Screen1.initialize
- Add LocationSensor1.ProviderLocked to true, LocationSensor1.ProviderName to gps in the Screen1.PermissionGranted block.
Thanks for guiding me.
