App on the Crystalsky gives "session expired error" and says to log out of my account and log in again...but how?

I purchased Litchi about 18 months ago and am going to start using it. Installed and updated it on my Crystalsky and when I open the app I get an error: “Your session has expired. Please log out of your Litchi account and then log in again to refresh your session”. I cannot find a way to log out/log in through the app. What am I missing?
