Everton does not display Google Maps data reliably in two cases.

Shortcode:
[add_eventon_evmap map_type=”upcoming” number_of_months=”24″ hide_past=”yes” map_height=”600″ show_et_ft_img=”yes” hide_end_time=”yes” lightbox=”yes” evc_open=”yes”]

Case 1:
The parameter evc_open=”yes” automatically opens the selected event which was selected in the map.
However, neither the featured image nor the map content is loaded.
Instead, a grey-white map-symbol appears.
If you close the event details by clicking on the header and then reopen them with another click,
both the featured image and the map content are loaded correctly.

Case 2:
The Google Maps overview with all events only loads in some cases.
In others, a grey-white map symbol appears.
At the moment, I cannot identify any consistent pattern.
The issue occurs across different browsers, in private windows, and both with cleared and existing caches.
