Doesn't store offline analytics

Hi, I'm using this for my WPF app. But running into an issue where I can't resend analytics that were tried to send while offline and restart the app when online.

Please advise.

Sorry, @d-haxton just noticed this. I will be working on ironing offline mode this week.
