New update problem of iPhone 5s :( – Mobile Music Sequencer - US Review

After update the app no longer restores purchases, it says "the app can not connect to the internet or no internet connection"... Because i like this app i purchased everything in it and now if the problem will not be fixed that will be sad:(.... Also i don't know why this up it became a battery drainer. When i start the app my phone turns hot and the battery drains 50% in about 15 or 20 minutes, this is crazy!!!!
