Steps to Reproduce

Configure the DotNet SDK as follows:

SentrySdk.Init(options =>
{
   options.Dsn = dsn; //dsn for a specific project
   options.AutoSessionTrackingInterval = new TimeSpan(0, 0, 30);
   var flavor = //get build flavor
   options.Environment = flavor switch {
       BuildFlavorEnum.DEV => "Development",
       BuildFlavorEnum.QA => "Quality",
       BuildFlavorEnum.STAGE => "Stage",
       BuildFlavorEnum.PROD => "Production",
       _ => "Unknown"
    };
   options.Release = <Release>
   options.InitCacheFlushTimeout=new TimeSpan(0,0,0);
   options.SetBeforeSend((sentryEvent, sentryHint) => {
       scope.User = new SentryUser() {
       //Set user id
      };
      // if there is a need to attach a file then attach a file to an event. In some situation.
     {
     var filePath = GetFileToAttach();
     sentryHint.AddAttachment(filePath);
     }
     return sentryEvent; 
   });
}); // end of init.

Deploy the app on Android and ios devices.
Run the app.

Expected Result

Release health sessions are sent for both Android and ios devices.

Actual Result

Release health Sessions are not sent from ios devices. The project also did not get any events from Native ios code (sentry.native.dotnet or sentry.cocoa.dotnet).

The DotNet layer does not send sessions health because options.AutoSessionTracking is not set to true in the SDK initialisation. If the underlying Android SDK is able to send this information, we expect the Cocoa SDK to also be able to send it.

Auto release health should be on by default on Android and iOS. In both cases from the .NET layer, not the native one
