we have developed an corporate mobile app for iOS. We are using Apple Business Manager and it is connected to Intune company portal.
I have published the app in the app store connect using private distribution mode.
I can see the app in the ABM and I was able to successfully install the app to a managed device via Intune company portal. When I tried to install the app on an unmanaged device using the web version of company portal I got an error saying that I have to enroll the device to install the app.
