Connection.Close() taking 5 seconds

I'm using an iOS device to print to a ZQ310 via a Bluetooth connection. The app is written in Xamarin Forms and C# using Zebra.Printer.SDK v.2.15.2634. The Connection.Close() command is taking 5 seconds to complete which seems longer than the previous LinkOS_Xamarin_SDK version?  Is there a way to control how long the Close command will take?  In the debugger I can see a property on the connection called "TimeToWaitBeforeClose", but I'm not able to reference it or override it in my code?  Is that something that I should be able to do?  If so, some sample code would be appreciated.

Thanks,

Elaine
