Crash on Android 9

Hi, we are having some issues on Android 9. We are using Unity 2017.1.1p4 and Unity IAP 1.20.0 (we had reports for the null currency bug before but that one was fixed in this version and it seems to work).

Here is the issue:

Code (CSharp):

1. Sep 9, 4:00 AM on app version 67
2. Google Pixel 2 XL (taimen), Android 9
3. Report 5

Google considers the crash rate to give us a feature or not and one of the main reasons for crashes right now is this one but we don't understand what is happening here.

It only happens on Android 9 (at least in the reports) but we have devices (pixel xl) with that android and can't reproduce the issue, maybe because we are testers, dunno (will try without being a tester)

I have more stacktraces but all say the same, the affected devices are:

Pixel 2 (walleye) 24 60.0%
Pixel 2 XL (taimen) 9 22.5%
Pixel (sailfish) 7 17.5%

Thanks

 

We believe this due to a recent security update by Google that we are investigating https://www.droid-life.com/2018/09/...ity-update-goes-live-for-nexus-pixel-devices/
