At the top of the Design Home page there is a preview feature to check out the design on a desk top, a tablet and a cell phone. We have found that they flash briefly, and then disappear entirely. However, very occasionally they will start to appear; once on the cell phone preview it was visible long enough to begin scrolling, then bingo nothing. On my computer the Statcounter number will appear which is visible in the footer. Can you suggest why this might be occurring and what to do to correct it?
