PS5 deluxe edition - Can't Play, only lets me play round with Scottie Scheffler

There's another thread about this but thought I'd join this gang as well. Brand new Play Station 5, bought the disc version of PGA and then it downloaded the updates. PS5 is plugged into the TV at home and on the wifi. Everythign seems to be working - internet says connected all green good to go.  Can only play as Scottie S at the Masters. No instructions or practise challenges. I'll admit I started to play before I realised I even needed to create an account on ea.com there was nothing in the instructions about that but have now done so,. Second time we try and play (and explore more options) Variety of error messages but the main one being unable to connect to EA servers (top right) and something else about "checking to see if this content is gated?"

I've read over 300 posts on the same subject so it would seem we are not alone. Can EA / Sony Playstation please either fess up or just tell us they don't know what is causing it. Then we can all stop asking for a solution.
