Hi mano36,

Welcome to Apple Support Communities. We ask that you follow the troubleshooting steps below.

• "Open the App Store and sign in. If a blue account button appears at the top of the App Store, you might not be signed in. Tap it and sign in with your Apple ID. Learn what to do if you forgot your password.

• Check your payment method. You might need to have a payment method on file, even if the app that you want to download is free. See what payment method you have on file and make sure that it isn't expired, declined, or failed.

• Restart your device Restart your iPhone or restart your iPad. Then check to see if you can download or update apps.

• Contact Apple. If you still can't download or update apps on your iPhone or iPad, contact Apple Support.
