It appears that EA has done something server side that has resolved this issue. It also appears to have fixed the issue on previous Fifas.
Thankyou for finally resolving this EA.
Thanks for confirmation on the FC Points @Bzapppp I never been able to play Volta at all. FIFA 23 I bought back in December in game from FIFA 22 discount when they promoted at like £14. When I got it my friends could play Volta I could never get on. The odd times it had worked when checking the store but if I go back out and back in I would have got “There was an error accessing server data, please try again.” When I played FC24 beta it was all working which I thought they fixed the issue so I have got the game but I’m getting same message before. I have raised cases through to EA support and got to the chats and they either won’t respond or can’t answer why it’s doing it.
@GHOST_2O42Hi. Can you "Me Too" my thread here? The more that do it the more likely they are to care... I hope
