The account name is not your name. If NatWest is rejecting the connection because of a name mismatch you need to make sure your name in 212 is the same as the name on your bank account (not the bank accounts name itself, but your name)
I changed my name on Trading212 to match my full name, and it doesn’t work. It appears as though this check might be happening on T212’s side, as NatWest approved the connection and I am able to select my accounts and click continue, all the way to being redirected back to T212.
… this is literally what this post is about. I am well aware the difference between account nickname and actual bank account name. After checking with NatWest the format on my account is indeed e.g. Smith RJ as opposed to Robert John Smith. What 212 are investigating is whether they can change on their side to recognise this format.
No this is incorrect. Spoke to NatWest about this in detail yesterday, they confirmed that for the connection Truelayer use on the account type I have, they pass through the full name in format e.g. Smith RJ as opposed to Robert John Smith. Nothing to do with account nicknames, just needed the format adding on 212 side.
