Clearing cache or data from an app can fix some software problems. If you clear data, any data stored in that app is lost, such as settings, login information, and saved games. If you don't want to clear the data, try just clearing cache first. If you still experience problems, then clear data too.
Tap Clear data and then tap OK.
