I am in the same boat. Recently started playing the game after a 3 year hiatus after getting a PS5. Game plays so much better. I than saw all the new content in multiplayer and decided to get a leg up and purchase some Andromeda points. I initially asked EA for help, but was just told they can't do anything, stating that it was all on the Playstation store. I spoke with a very helpful tech at the Sony store and will try the solutions presented to me.
First step. Restore the license on your playstation in the settings menu.
Second step. Deactivate the console, then reactivate the console. Do this by Settings>Account Management> Activate as your Primary PS4/PS5
Once you have done these steps, you can boot up the game and see if the Andromeda points are activated.
The real kicker is that the Playstation rep informed me that if all of this is complete, and it doesn't show up, that it is a PUBLISHER issue not pushing the content over to you.
Side notes:
I run the APEX HQ app on my phone as well, so there is no issue with my account not matching up with EA and my Playstation.
Both the PS4 and PS5 do not have Andromeda points show up.
Andromeda points purchased through the PS5 store on the console (refunded by Sony), and second time through the Sony Website (Still pending)
