We have an enterprise application which customers are using since long. Suddenly some customers have reported they are unable to open app in iOS 18 OS. On lower versions like 17 it is working fine.
We have a deploy this enterprise application on our server from that link our customer can download and install the app in iPhone. Now they are blocked due to this error. After installing the app when they open app below error message is shown to them. "AppName" is no longer available.
Let's first figure out if your issue is caused by an issue with the app build you are distributing, or if it relates to the server you are distributing the app from. Please test using the instructions in Distributing your app to registered devices to use Xcode to install a distribution build onto your devices. This testing with Xcode is not the same as the development build-and-run workflow.
If your app installs correctly to your iOS device using Xcode as described by that document, then the issue isn't your app, but something with your over-the-air distribution server setup. Please let us know the results of your testing.

Thanks for your reply Ed Ford, but i don't think so this issue is related to our server link. This app we have put on our server since more that 2 years and from that link our customers are downloading and installing the app. As this is enterprise account app so after installing the app user has to Trust the certificate from their iphone then they are able to use it.
Also user's having ios 17 or below OS are able to download and install the app successfully from the same server link and they are still using the app. Only issue happening with iOS 18 and above versions. User's haveing iOS 18 or above not able to use the app.
