Tablet "Share" pod showing "Tap to view"

Hi,

On iPad and android tablets using the connect app, sometimes the content of the "Share" pod (an image) shows as "Tap to View" when changing layouts.  It will sometimes load perfectly, other times not at all and just show the "Tap to view" message.

We are still in testing, on a relatively high spec stable connection, so I can't imagine that it is bandwidth related at the user end.

Thanks

Owen
