Version: (Business Edition)

Xamarin Studio
Version 5.9.4 (build 5)

When trying to initialise Google Tag Manager, the app crashes on iOS 9 beta - 4.
In particular, it fails on line:

TAGContainerOpener.OpenContainer(code, tagManager, TAGOpenType.PreferFresh, 2, this);)
Try / Catch exception is not caught, as this seems like a catastrophic failure. However, last piece of info from iOS logs show some info:

Jul 28 18:03:45 iemcinipm2 symptomsd[94] : __51-[FlowAnalyticsEngine _applicationStateMonitorInit]_block_invoke Can't convert appState from dictionary {
BKSApplicationStateExtensionKey = 0;
SBApplicationStateDisplayIDKey = "xy.z.abc";
SBApplicationStateKey = 0;
SBApplicationStateProcessIDKey = 246;

=> Components.

FWIW this looks like a bug in the native library itself, and not in our bindings (and should thus be reported to Google).

Please see updated comment from a colleague of mine on the xamarin forum post. It does infact look like a xamarin bindings issue.
Comment 3 Israel Soto [MSFT] 2015-07-29 21:10:30 UTC
I will report this to Google.

Meanwhile, the workaround of this is using null or numbers with decimals (e.g
0.1, 2.1) in the timeout parameter. Using numbers without decimals (e.g 1, 2,
2.0, 4.0) will terminate the app.

This issue is fixed in version 3.10 and above
