Thank you for getting back to me. This is the issue:
I worked on my desktop doing edits by that I mean adding banners and updating pages.
Then i went to my phone to see how it looks on mobile and I was not able to see my changes. What I saw is the website I did BEFORE the changes, edits and updating pages.
I refreshed my phone and the website remained looking as the old version I created.
You didn’t need to edit to add banner images in pages. To add banner images, you need to add Text widget on Banner Wide Widget position. And on the text widget content area you can add html tag for images as shown below:
If you want to display banner images in specific pages then you can use Jetpack widget visibility plugin. See for reference :How to show/hide widgets on pages?
If this didn’t clearify your doubt then please let us know, we are here to help you.
