We’ve a 2.5MB KML file that we update at midnight every day. Will this plugin allow us to refresh that KML file only daily but otherwise not have to load a 2.2MB KML file every time someone visits the site?
Any special settings or “hacks” required?
Yeah, you can update your kml layer on a daily basis, You have to insert KML layer URL on a map backend settings and save it. Please check this guide tutorial https://wpgmp.flippercode.com/docs/how-to-inlcude-your-kmlkmz-file-in-your-map/ for more help.
