Hi,
I am experiencing an issue with in-house apps on iOS 18. When the MDM profile is removed, newly installed in-house apps cannot be opened. However, previously installed in-house apps still work fine until the device is restarted.
Context:
Our in-house apps are not distributed via MDM but through an internal company app store. These apps are signed with an enterprise certificate and have been working fine on previous iOS versions.
Steps to reproduce:
- Install an in-house app while the MDM profile is active -> The app works fine.
- Remove the MDM profile.
- Install a new in-house app (signed with the same enterprise certificate)
- The newly installed app does not open at all.
- The existing in-house apps installed before MDM removal continue to work normally.
- Restart the device.
- Now, even the previously installed in-house apps no longer open.
Observed behavior:
The newly installed in-house app does not open, and no trust prompt appears in Settings > General > VPN & Device Management.
The previously installed in-house apps continue to function normally until the device is restarted.
After restarting, none of the in-house apps open anymore.
Is there a now restriction in iOS 18 regarding in-house app installation after MDM removal? Any insights or solutions would be greatly appreciated!
Thank you.
