Sometime, you may see the page like below after installing DeployGate on your iOS devices.
In this case, developers need to do some work for the delivery of apps to your device; which is called "Device Provisioning". Please ask your developer to build an installable app for you.
Completing this process may take some time.
Please contact your developers directly. After device provisioning is completed, you will get notified and instructions to install apps via email.
