Unable to Verify App

I have deployed an in-house enterprise app to a user and they are unable to open the app. The error is "Unable to Verify App" An Internet connection is required to verify trust of the developer <developer cert name>. This app will not be available until verified.

The user is connected to the internet via wifi. We also tested with a cellular connection. We are able to browse the internet so, we're sure the device is connected to the internet. The app downloads but, when the app icon is clicked the error appears.

The same app deployed to several other users does not produce an error and opens without issue.

What is causing this error and how can we fix it?

I am suffering from the same problem. On my iPad, if I initialize the iPad, it resolves once, but then it happens again. This issue occurs with iPadOS 16.6 or later. Same issue, Related thread :https://developer.apple.com/forums/thread/736905?answerId=775995022

It does not look like anyone has solved the issue. We are using an MDM and according to apple "If you install an app by Mobile Device Management (MDM), trust is automatically established." ( https://support.apple.com/en-us/HT204460 ) but that is not the case.

I was able to get the app to launch on the problem device by having the user delete the app, wipe the device, and restore from backup. The user restored the device from an iCloud backup and was then able to download and install the app. The Unable to Verify App error no longer shows up when launching the app.
