I did find that by enabling Compatibility Mode in my W3 Total Cache (in Page Cache | Advanced Settings), this improved MobilePress’s behavior slightly. Although it still brings up Posts rather than Pages as I told it to – it is now displaying a dropdown of pages at the top so the user can select a page to go to. So that’s at least a STEP in the right direction.
I can’t help but I am having the exact same problem. Any thoughts about what we’re doing wrong here?
