I'm trying to install and setup the plugin for running on an iOS device on my existing project. Following the guideline, I have created a GameObject and and added the script with a public GoogleAnalyticsV3 using GAv3.prefab. Android Tracking Code, IOSTracking Code, Product Name, Bundle Identifier, Bundle Version have already set with
Dispatch Period: 5
Sample Frequency: 100
Debug Mode: VERBOSE
Anonymize IP: false
Dry Run: false
Session Timeout: 1800

Then when running on iOS device, I got an EXC_BAD_ACCESS in
File: GAIHandler.m
Method: void send(const char* parameters)
Line: 244
Statement: NSString *attris = [NSString stringWithUTF8String:parameters];

Not calling any function even DispatchHits() or StartSession() gave me the same result. I have also tried to log the tracker and got (null).
What I have missed? Please suggest me to figure out this issue. Thank you.
