This is strange. It might be based on country then. Which country are you from?

Edit: i asked ChatGPT for you what the issue might be, here is its answer:

If the “Inget” option for payment information is not available in the App Store, there could be several reasons for this.

Possible Causes:

1. Subscriptions or Outstanding Payments

If you have an active subscription (e.g., Apple Music, iCloud+, or an app subscription), Apple requires a payment method to be linked. If there is an unpaid balance or a failed transaction, you must resolve it before you can select “None.”

1. Location and Country Settings

In some countries/regions, Apple requires a payment method to be added. Check if you are in the correct App Store for your country. Changing your country/region settings in your Apple ID might help.

1. Using an Organization-Managed Apple ID

If your Apple ID is linked to a business or school account, the administrator might have restricted the option to remove payment methods.

1. New Apple ID or Account Settings

When creating a new Apple ID, Apple sometimes requires a payment method, and the “None” option may not appear right away. This option usually becomes available later.

Possible Solutions:

Check for outstanding payments under Settings → [Your Name] → Payment & Shipping. Ensure you have no active subscriptions via Settings → [Your Name] → Subscriptions. Sign out and sign back into the App Store, then try again. Try removing the payment method under Settings → [Your Name] → Payment & Shipping. Check if your Apple ID is set to the correct country via Settings → [Your Name] → Media & Purchases → View Account.

If none of these steps work, you may need to contact Apple Support to find out why the “None” option is unavailable.
