I’ve added 2 extra fields and followed the tutorial here to do them. > https://www.wpmapspro.com/docs/how-to-create-extra-fields-for-location-infowindow-2/
However this tutorial no longer appears current as my Infowindow Settings look to have a new design with several premade templates rather than a way to add just the custom fields as suggested in the tutorial.
Is there an updated tutorial or documentation?
Secondly the background of my Infowindows are transparent and unreadable.
