Having issues with cross progression

Heya,

I'm not sure with what information Customer Support is operating here, but to me it looks like they are still using outdated information.

When Cross Progression rolled out (& Now), you would not have needed to do anything to 'transfer' any of your progress.
What Cross Progression aimed to do, was to bring all the data from the Platform Accounts to the EA Account itself*, so that any platform account connected to an EA Account would get the progress from the EA Account, making it possible to access all your in-game content on all the platforms.

You should be able to access your PS5 content if you log in with the EA Account on the EA App, or with a Steam account linked to the same EA Account that your PSN account is connected to. How are you currently trying to access the content from your PS5? (What platform are you playing on? That kind of stuff)

Are you sure you are using the correct EA Account on PC? You can see which Platform accounts are connected to an EA Account on this page: https://myaccount.ea.com/am/ui/connected-accounts
Make sure the correct PSN account is connected to your EA Account.
