We were recently contacted by the Google Maps API team, and were unfortunately told that showing live Google Maps previews inside of the Designer would only comply with their Terms of Service if we upgraded to a very expensive Premium level plan, which is not financially feasible for us. In order to stay within the limits of the Google Maps API Standard Plan, Webflow will soon stop rendering map previews when you're logged in to the Webflow Designer - instead showing a placeholder of the same size in the place where the map will render after publishing.
Here are some examples of maps before and after this change:
Inline Map (Before)
Inline Map (After)
Styled Background Map (Before)
Styled Background Map (After)
We realize that this is not the ideal way that maps should work inside the Designer. However, we have to make this change very quickly to comply with Google's request - once we have more time in our development schedule, we'll create a more robust solution that brings back map previews again.
Note that this does not affect maps displayed on published sites or sites access via the client Editor - maps should continue rendering there as before.
This change should go live on Friday, March 31st.
