Updating Zus

Simple question. My ZUS app keeps telling me I need to update it. How do I do that?

What is the exact message? And when do you get it exactly?

If it does not automatically update depending on what phone you have you could go into your App Store and update the app that way or you can try deleting the app keep in mind you need to remember your login and password and reinstall it and it should install the new updates check your settings on your phone in your App Store
