@Quinn Thanks for your timely guidance, the problem I'm having is a bit different in that I have two app groups, "TeamID.mydomain" and "group.mydomain". If only one of them used, everything is ok, but if I add both app groups at the same time, App Store Connect fails to validate and returns errors. I need to do a data migration, so I have to use both app groups at the same time 🤣

I check the manual provisioning profile, "group.mydomain", the iOS-style app group were included. But it does not work.
