I published this bug days ago (manual ads are not shown), and it is not a compatibility problem with other plugins or themes, it happens in several themes, even using the classic editor.
On some environments, it work format <!–AdsX–> but not [quads id=X] shortcode
if set to NOT insert ads by default, manual ads ([quads id=X]) are not displayed
Tested on several websites like https://portalinfonavit.com.mx/
Yo acabo de actualizar y ha dejado de cargar las imágenes del slider aquí… a ver si lo solucionan porque es bastante malo que una actualización deje sin funcionalidad algo tan visible como un slider.
