As others have had this issue with Modern Events Calendar plugin and its Google Maps function either always loading or not at all despite full user consent (yes to statistic cookies), here’s a new request to solve this issue.
First Google Maps was always loaded regardless of user consent. Then I added the MEC gmap link [/wp-content/plugins/modern-events-calendar/assets/js/googlemap.js] to the Script Center to block in Category Statistics with Placeholder enabled. Now nothing is loaded at all, not even a placeholder, if I agree to statistical cookies in the banner. Caches cleared etc. Seems complianz is promising too much for what in reality requires extensive customizing.
jarnovos actually had provided a link [https://raw.githubusercontent.com/Really-Simple-Plugins/complianz-integrations/master/webnus-modern-events-calendar.php] to a snippet to solve the problem a year ago but that link has vanished for no good reason. Why do you post solutions and then delete them later?
