Unlocking of a new L2 account with Metamask/Ledger is not possible

[Martin0021]

Hi Team,

I transferred some ETH to a new L2 account. I'm trying to unlock now the account, but there is an error with the second signature - it fails.

I'm using Metamask with Ledger HW. Btw, the first signature succeeds. It's just the second signature, which fails.

Please advice.

Many thanks!
