The last time it took them about 4 maybe 5 days to approve. Now we see that there is yet another iOS update (9.0.2) and we will be testing the program against that update also once we release the current app update. And it's all over again, if Apple decides once again to release another update.
Thank you for the kind words. Yes, we do our best to update the mobile version as soon as possible to fix the iOS 8 issue. Meanwhile, if you are using iOS 9, the app should be working ok. Please, let us know if you have any issues.
