In our Enterprise account with Admin access, I can't see the option to create a DeviceCheck key needed for the App Attest functionality.
Is there a limitation preventing this key from being generated on Enterprise accounts?
At this time, DeviceCheck functionality is not available to Enterprise accounts.
Although, we would like to understand your use case and needs. If you would like Apple to consider adding such support in the future please provide feedback via https://feedbackassistant.apple.com to make a request.
