Free Personal Team, hitting "Your development team has reached the maximum number of registered iPhone devices." I need a local build on a physical device for a demo, so I'm looking for the fastest supported path rather than a fix for the underlying behavior.
Context: I hadn't used this Apple ID for development in about two years, so the usual "wait a week for registrations to expire" advice doesn't seem to apply here. The registrations appear to have persisted well past that window.
Already tried: removing and re-adding the account in Xcode, clearing ~/Library/Developer/Xcode/UserData/Provisioning Profiles, deleting the developer profile from the device, and confirming this isn't the separate offloaded-apps issue that causes the "maximum number of apps for free development profiles" error. Free accounts have no Devices page, so there's nothing to clear manually.
I'm aware of two options: enroll in the Developer Program, or create a new Apple ID and use it as a fresh Personal Team. I've also seen reports of people calling Apple Support and having devices dropped manually, with mixed results.
Is the phone call route still viable for someone on a free account, or has that closed? And is there anything else I'm missing before I go the new-Apple-ID route?
