EA FC24 on switch is asking me every time to reset password

@Ronref99 Hello. I had the same problem. In fact, there was already an EA account (FIFA 2018) and Nintendo somehow remembered it and kept using it even though I had unlinked it in the Nintendo Account and relink with FC24.

Luckily, I was able to remember my old email address because both my email address and Nintendo ID had changed at Nintendo in the meantime. However, the old Nintendo ID is still stored at EA, which is why EA Support could not find my Nintendo ID in their systems.
