My phone is not letting me make in app purchases but in app purchases is allowed

Hi Dominate_13,

You started from a great resource: If you can't find or use your in-app purchases

For help with making an in-app purchase, be sure to also check your payment method is valid with the steps below found in the article here: If you need to change or update your Apple ID payment method - Apple Support

"Update your payment method on your iPhone or iPad

1. Open the Settings app.
2. Tap your name.
3. Tap Payment & Shipping. You might be asked to sign in with your Apple ID.
4. Tap Add Payment Method, enter the new payment method, then tap Done.
5. Tap Edit.
6. Tap the red delete button next to the old payment method, then tap Delete.

"

If the issue continues as you've completed the steps in the article you started from, reach out to Apple Support directly to further assist.
