I LOST MY FUND EVEN ALREADY IMPORT WALLET I cannot recover my fund in Copay Wallet. I done import wallet using my back up 12 phrase word but yet still cannot recover. Why?
Check the wallet version, was it copay the wallet you initiated the seed from? If not, the derivation path for your coins may be different, please check: https://walletsrecovery.org/
They've changed multisig derivation few times, I think there is a link to recovery tool for older versions.
Be aware that your mnemonic is dependant on the arrangement of the words, they have to be imported in the direction from 1st to 12th.
