I work on an app that has the com.apple.developer.mail-client entitlement. We're interested in trying out Xcode Cloud, and one of the project and workspace requirements is to use automatic code signing. We do not do this at the moment because it's not compatible with the additional entitlement.
My understanding is that we can migrate to automatic code signing if we migrate the additional entitlement to a capability and that to accomplish this our account holder needs to submit a request (see the last section of that page).
We submitted the request a little over 3 weeks ago, but so far we haven't heard any updates. We also tried reaching out directly to the email address linked in the com.apple.developer.mail-client docs, but have not heard back.
We're now posting here to see if anyone can provide some guidance on whether there are other steps to complete or contacts to whom we should reach out. Thanks!
