Have you tried restoring your 2FA wallet with the 2FA seed and "Keep"ing the 2FA functionality... rather than "Disable"? After it is restored, checking what xpubs it has... see if any of the three xpubs in the 2FA wallet are "xpub67z"
Yes I have the original word seed from the Mac. I need to be clearer on what I should do to set up the wallet. I get a little confused still when it is a 2FA, or multi sig wallet - for isntance how many cosigs to have.
So, if there are any (more) steps I must follow , like >"Keep"ing the 2FA functionality< please let me know> I will then give it a go.
