How do I cancel my fox nation subscription that I bought through the apple App Store on my iPhone bc I have followed all steps but when I get to the page that I’m supposed to cancel it at it just says, “expiring soon” and does not give a cancel sub o

You can keep using a subscription that was cancelled until the expiration date. Also see the following from If you want to cancel a subscription from Apple - Apple Support

You might need to scroll down to find the Cancel Subscription button. If there is no Cancel button or you see an expiration message in red text, the subscription is already canceled.

Also, a subscription that is already cancelled will typically have wording in fine print similar to "Expires on [date]" rather than "Renews on [date].”
