I can add my location to a PowerApps Map Canvas app, it appears as a pulsating blue dot on the right place.
It would be great if the map canvas could zoom / fly to this position, after the GPS receiver has found the first signal.
Is there any solution in PowerApps for it?
I'm not sure about the zooming other than hard coding this to a value, but for centering you could possible use Power FX and the Location values: https://learn.microsoft.com/en-gb/power-platform/power-fx/reference/signals#location This retrieves the users GPS location. You could then pass those into the current Latitude/Longitude fields of the map component.
