You should still see the standard OAuth/OIDC scope consent prompts. For example, when you request for "profile".
For Data Privacy purpose etc., did you add these to the Privacy tab of the application? Prior to migrating, requesting for those as, say, marketing/email.default would have simply treated it like any other scope consent record. With the migration, once you add the purpose in the Privacy tab, you will see that the consent record is actually "unpacked".
