It describes the functionality that should be in there: Automatically finding all kinds of wallets/accounts for a seed phrase on the Trezor. And the ones from ccvault (and/or other wallet apps) should show up under “Legacy Accounts” according to that. ?♀️ Have you tried the Trezor support?
Hi I found my wallet in "hidden wallets legacy account" section. I had to enter my passphrase and it popped up!
