Hi,
I have both Pro and Community, in addition to the main plugin. I think I found a sort of bug: if I update venue informations from a community edit venue page (for example, /events/community/edit/venue/{venue_id}/) the map isn’t shown anymore. I went to see what happens in the database when a venue is updated using the community plugin, and i found that in the wp_postmeta table the following post meta are setted to false, without any user request: _VenueShowMap, _VenueShowMapLink.
To ensure that it’s not a bug of my theme, I did the same things in a new wordpress installation, with twenty fourteen theme and I found the same problem.
Thank you,
Giovanni
