It's the same on all iOS devices, and it's been an on going problem for years.
It's actually quite incredible that they refuse to acknowledge the problem. I've phoned a few times, and the response I got was that it's not a problem, despite people complaining and posting on this forum for years. YES YEARS!
Clearly they can't figure out whats going on, and because it can work, all be it with much frustration, they refuse to acknowledge that they even have a problem.
Maybe that's why they starting giving a way their crappy apps for free. Unfortunately I payed for both my iPad and iPhone apps, and I'm ******. Totally unusable and no recourse, just a big rip off.
The only saving grace is that it works great on my macbook pro.
