I think this is a bug but I've never seen it before. I have a page where I have updated a photo. The photo is the same for each of the screen sizes down through mobile. The page has been published and re-published.
On my computer, it shows the correct photo as expected. When I shrink the window size through all 4 resolution it continues as expected. On my phone (tested on Android and iPhone) it shows correctly when I navigate to "www.MyURL.com". However, when I remove the " www." and navigate to "MyUrl.com" it shows the old photo. The URL change makes no difference when viewing from my computer.
I look forward to any assistance with this issue.
