Hi all customer,
After import demo data or move your site to another server maybe you will get a common issue of Elementor is Backround Image of section, column,… doesn’t show on Mobile devices.
First you need to understand Editing Elementor on Mobile follow this:
After setup all settings on Mobile but images background doesn’t show please go to: Elementor -> Tools -> General. Click on Regenerate Files & Data and Sync Library and Save Changes.
Maybe you need to clear caches to see changes.
Hope this helps and thanks for reading!
