To ensure you have all the available MySparklight app features, you'll want to keep your app up to date. To find your mobile app's version, you can go to the Account tab. The version will be at the bottom.
Compare your version with what is available from the app store to see if you have the most up-to-date version. Typically, when you do not have the latest version of an app, you will find the option to update it when you search for it in the app store.
You should also see an alert at the top when you use the app if there is a newer version.
