App settings missing iOS18

We use a credit card processing app in conjunction with a data base. when you navigate to the app in settings we can change the host and file name for the redirect. it works perfectly in IOS17 but not available in IOS18. This is defiantly an iOS issue because I have found the same issue in another up that uses these same setting, they are missing too in IOS.
