I don't know if I am doing something wrong, but after closing and reopening Windows Phone application, the state of Application.Properties is not cleared, but reset to some previous state. I am keeping information about logged in user and some other data like last update check and hash.
Even though everything appears alright while the application is running, when closed and reopened, I lose recent changes and I have the same properties I had when I entered the application before.
It is as if new properties don't get persisted. Properties are of string, int and List type.
Also, when redeploying my app, data is often times completely gone. I am on Xamarin.Forms 1.3.1.
