I’m using the “featured image” as the masthead image on my blog pages, but the images are not loading consistently. Especially on mobile. I’m using the default blog post theme template. And the image sizes are not an issue as they are well under 1MB each. Thoughts?
Mind sharing a link to your website so we can investigate?
I tested on mobile device and it is able to load. Did you try different browser or different device to see if it is an issue specific to the device?
