Hello Everyone, We have an App which we have been developed only for our internal employees and the app would only work when device is connected with our intranet. This App would be distributed via our MDM on devices of the authorized users. We tried uploading the app on app store but was rejected as they could not validate the App. we tried providing them the vpn connectivity as well, but Apple team refused to connect using vpn. Now we have learned that we can take the Apple Developer Enterprise Program. now we want to clarify following: a. While in some forums it states that Apps under Apple Developer Enterprise Program does not need to go through the App review process. Is this correct? b. Can we use our existing MDM for distributing the App to authorized users? c. If (a) and (b) are yes, What steps are needed to ensure that we can distribute the app without any issues? A quick help on this would be very helpful
