Google Maps is great but it's restricted, frustrating and ultimately they're using your data to sell you adverts and track what you do. SO... import your data to Pin Drop and really make it your own and selectively share what you create with others.
To import your Google My Maps data, you will need to download a Google Takeout file.
You MUST include this in your export as this will guarantee you import your pins as expected.
