How to get forza rewards credits

In the other forza games there is a message option were you can get your gifted credits and stuff. i dont find this in horizon 3. how can i get the gifted credits from forza rewards?

i know that some gifts are being notificated in the social tab in the game atleast. Or maybe try checking that forza hub app?

having same issue on Win10 version, clicked to receive reward credits in Forza Hub but they never showed up in game

its working now on xbox. its in the social tab. but i did not had access to it before the patch.
