Sadly I too have been having the same problems with AA. The app says go left, and AA says go right. Then the circle going round and round, and nothing happening at all.
The App on it's own ( apart from a 5% drop in battery power in less than 15 miles, which is plugged in via a USB in my Mitsubishi car, which rather renders the app use, a bit problematic to use over a long period of time ) is brilliant.
I love MRA, it's the perfect planning tool to use. For me nothing comes close. Basecamp, which I can also use without any problems, is OK but the various maps that MRA offers is light years ahead of Basecamp. I too wish that this ongoing problem would be sorted out soon. But having said that I firmly believe that the MRA team will get there in the end, of that I've no doubt.
