With the introduction of iOS 9, Apple slightly changed their security guidelines. This makes it necessary for you to mark PressMatrix as a trusted developer in the settings of your device.
- When you first open the Preview App you’ll see a notification that the developer of the app isn’t trusted on your device. You can dismiss this message but you can’t open the app.
- Now switch to „Settings“ > „General“ > „Device Management“. You should see the PressMatrix profile .
- Tap the profile to establish trust for PressMatrix.
- You’re then prompted to confirm your choice. Once you trust our PressMatrix profile, you can manually install other apps us and open them immediately.
