iOS crash - After IAP

Integration latest version OneSignal and Unity in-app purchase. After integration I send InitiatePurchase(product), application crashed. In xCode I see
[OneSignalTrackIAP respondsToSelector:]: message sent to deallocated instance 0x17401fe40

We are experiencing this crash as well. It is crashing on iPhone 7, but not iPhone 6s, both running iOS 10.2. The above message happens with Zombie checking enabled.

I experiencing this crash on iPhone 6s and IPad Air, iOS 10.2

No

@lestardigital @pmaloka @jay-neb Thanks for the report, can you check if OneSignal is being initialized more than once in your app?

This issue is most likely the same as the one below.
OneSignal/OneSignal-iOS-SDK#169

It is now merged into the main native iOS SDK and will be included in the next Unity update.

@jkasten2 Yes, OneSignal initialized once in app

@jkasten2 Thanks, problem resolved

If a short period of time to send the purchase of two times in a row and it does not completed first purchase, get an application crash. Even with one initialization on iOS push notification comes twice

@lestardigital I believe the change in my link above will fix the issue. We will release an update the beginning of next week with this fix include.
