To get the latest Zucoin wallet app update, all you need to do is close the app on your device, then re-open it.
Don’t delete the app, just close all instances that are open.
Next time you open the app, it will automatically trigger an update to the latest version.
If you’ve completed this step and the Zucoin wallet app still hasn’t updated, then it’s still open somewhere in the background.
After following the above steps, your app will now be updated to the latest version.
