What to do

- Open the app store's own updates/downloads section and cancel then retry the specific update.
- Sign out and back into your app store account.
- Check that date and time are set to automatic in phone settings.
- Uninstall and reinstall the app as a last resort if the update still won't apply.
When to call a pro
If no app will update across the board, contact the app store's own support, as it may be an account restriction rather than a device issue.
