Getting errors when trying to migrate KNCL to KNC at

When entering the amount of KNCL to migrate, and clicking “approve” I get this:
This is a Chrome message and when I close this window, I then get this:
I have no idea what either message means and have no security key in Chrome. Does anyone have any idea what I am doing wrong?

It could be an issue with your Ledger? Ledger’s new update has some issues with Metamask and Chrome. Have you downloaded Ledger Live and updated your firmware and Ledger Live apps to the latest version? Make sure you write down your seed phrase and Ledger Live password first (and don’t share them with anyone)

I am having the same problem. Did you get an answer on how to over ride this chrome message?
I’m not sure whether it is a problem with my Ledger Nano S but I have checked with them and they believe it could be a Kyber migration problem??? Any answers?

The only response received was the next day, suggesting that perhaps it is a problem with the new update having some issues with Metamask and Chrome and suggesting that I check that I have the latest version.

So was it? Or are you still getting the same error when trying to migrate?
