Good morning friends. I use a Mini iPad at my parties. I continually have problems with it buffering (is that the correct term) as I'm trying to put in orders. I thought it might be this particular device, so I took my husband's iPad to last night's party. Fine at first (which is what would happen with my mini) but then it started buffering (right when I had a customer with a credit card. . . so I got to write down all her info instead of just swiping ). I was able to finish processing the orders through my phone. So, is it my old iPads or something with the app/server? Anyone else having issues?
