With Street View Preview, you can check the preview image of the street view directly on the iSharing app. Turn on the Street View Preview feature to see the preview image in the bottom right when viewing your friend's location.
* Please note that Street View Preview is only available in areas where Apple Look Around is supported.
You can choose whether to display the preview image on your iSharing or not. You can turn it on and off as follows:
iSharing app > Menu > Settings > Toggle the switch next to "Street View Preview" on or off
