I was able to setup a release test for an iOS app for distribution using a web server. It works perfectly fine for all the devices I registered for the deployment profile.
However every time I try to distribute a Unity based Vision Pro application using the same process for building the package and set up for distribution it does not work.
Safari only shows a message telling me:
"Cannot connect to ."
When trying to install the iOS app from the same server it shows the message "Do you want to install ?" and installation completes correctly.
My iOS is a simple hello world app generated by Xcode.
My Unity app is an AR app targeting com.apple.platform.xros.
According to documentation there should not be any difference in deployment profiles/signing for iOS apps vs. visionOS apps.
What am I doing wrong? Any hint is appreciated how to continue.
