Please consider adding an option within the iOS version of the Vision app to allow users to select the Google Maps instead of the Apple default maps (see example photos in linked post above) when using the Ground Station feature. I believe the Androind version uses google maps which in my area are much better (less clouds, more detail).
Any chance that this could be added as a feature request for iOS users? The Google Maps are so much better in my opinion, than the Apple maps which are used by the iOS DJI Vision app.
Actually I noticed the satellite images are more out of date than when viewed in Apple Maps directly, which made me think that the source is not even Apple Maps.
