Reproduction:
Movies)Title)MoviesTitle's interface typeWhile I was trying to confirm that this actually worked on v9.0.0-rc18 I noticed that if you create a project with API from rc18 but then use npx directus start so that a rc19 app connects to the old backend, everything works as it should including new features from rc19 (m2a), so it would seem that the cause of this problem is not in the app's code but the api's
I have the same issue.
Seems that the interface is not set in the directus_fields table

Setting it to translations fixes the issue.
