In the Developer portal, I'm attempting to add the "DriverKit UserClient Access" to an App ID that is assigned to a DEXT that we are developing. Once I have filled out the form and clicked "Submit" the screen goes bank and stays blank even after a long delay. The original Capability Request tab's entry for "DriverKit UserClient Access" never changes from "No Requests". I have tried this on two successive days, with the same result.
