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.
This is the quickest and easiest way to share a Google My Map to Pin Drop. Find out more here.
You MUST include this in your export as this will guarantee you import your pins as expected. Here's a help article from Google My Maps.
