Thank you for your report. Actually, a lot of applications stopped working all of a sudden when Apple released their 9.01 update :| We did our best to update the app as soon as possible, and it took some time for Apple to review and approve it in the AppStore. They were very busy with this, as it seems, due to a lot of developer updates released at the same time.
Now we are continuing to fix some issues because Apple released the 9.1 in the middle of the approval of our application. So it seems like it will take use other few days to re-iterate with this.
