This seems to be incorrect.
I have tested this 3 times now with a Be a Pro and 2 different active roster Official Updates from EA. and I am not seeing the updated Rosters ( it still shows the playoff roster that NHL 25 would have had for its final update)
This has been as issue for years, I would say going back to NHL 22 if not from the launch of it; where the Be a Pro does not use any other roster but the default one that is launched with the game. Its one major reason why I stopped playing Be a pro to begin with as this ruins any sort of immersion with the mode.
I thought now that the revamp was done and you stated in this thread that all it needed was to use the newest roster update, that this issue was resolved. Sadly, that seems to be wrong.
Seeing you stated that it does work, can you please give me the step by step requirements I need to make sure it uses the correct roster in Be a Pro?
