Thank you! Worked for me.

Thanks for the quick response. That is the correct Team ID. This was pure user error. I should have read this thread a little closer. I'd entered the Hardware UUID instead of the Provisioning UDID. I think what threw me off is that Apple Developer device registration asks for 'Device ID (UUID)' which doesn't exactly match the system information fields. I guess I saw 'UUID' and thought it meant Hardware UUID. It asking for a UUID but actually expecting a UDID confused me. But purely user error.

Thanks for the quick reply. That is our Team ID, correct. This was actually purely user error. I should have read this thread closer. I'd entered the Hardware UUID and not the Provisioning UDID. A little confusing as the Apple Developer device registration, for macOS, asks for 'Device ID (UUID)' but is actually expecting the UDID. But again, purely user error.
