I can't update the app in my apple store

Hello~ What happens when you try? Messages or errors? In the meantime take a look here:

What device is this on? Try signing in with the account used to download the app. Try uninstalling or offloading and then re download the app

Hello,

Try completely uninstalling the application. It usually will reinstall with the newest updated version.

Hope this helps, if not let me know and we can do some troubleshooting.

How does that sound?
