Purchasing within a third party app

Today when trying to purchase packages within my third party apps today I began receiving a notification to come here for support, followed directly by a notification that the iTunes Store was unable to be reached. First time having this issue was today. I attempted a reboot to see if that would resolve the issue and had no luck. I have a credit card on file that is active and funded. I’m not understanding the issue so I would greatly appreciate any help offered and hope to quickly resolve the issue so I can purchase and enjoy what the apps have to offer. Thank you
