A provisioning profile with DER-Encoded-Profile will fail the signing verification on iOS 15 beta 1 and 2. From our internal testing, only Apps developed via XCode Version 13.0 beta (13A5154h) can be installed because only the provisioning profiles generated from Xcode 13 beta do not contain DER-Encoded-Profile Our build servers run Xcode 12 so all profiles contain DER-Encoded-Profile. This is impacting our organization's ability to test our internal Enterprise Apps for the preparation for iOS 15 support as all Enterprise mobile provisioning profiles have DER-Encoded-Profile.
