Hi Adrian,
It is likely ALL Caching Plugins, even those that allow for not caching for mobile devices and those that even have a WP Touch exception. Can't recall which one has that. We have tried the following with the same results:
W3 Total Cache
WP Super Cache
Quick Cache
Falcon Engine with Wordfence
If you are only dealing with one website then you can monitor it if you are visiting your site daily. If you are like us with hundreds of websites then I advise NOT using any cache with WP Touch Pro or Jetpack Mobile. We've seen it happen with both those mobile plugins and we don't have time for more in depth testing.
As time goes on we will be replacing all designs with
Responsive Designs. That way there is no issue with Caching. Right now DIVI from Elegant Themes is our favorite responsive design. Of course, we can now customize our own themes. If you're looking for a good one then I'd try DIVI.
