Sign in with Apple users migration

hi all, we have an app we want to move from Team A to Team B. We support Sign-in with Apple in the app so users need to also be migrated. We use Auth0 as the authentication solution.

I followed the documentation and generated the transfer identifiers like here. And I got HTTP 200 responses . However with a 'short' transfer_sub: {"transfer_sub":"000226.r52567d778d6641e78daf6977563ff09"} (it has only 2 sections, instead of 3). For all users.

I assume this then causes my request to exchange identifiers like here to return an HTTP 400 Bad request.

Does anyone have any idea on why do I get a 'short' transfer_sub ?

Many thanks
