Q. I selected Connect through Ledger but I cannot find my address in the dropdown. How do I resolve this?

This is a ledger issue related to derivation paths (ledger legacy/ledger live have different derivation paths). Unfortunately, ledger does not allow you to set a custom derivation path at the moment so the only way to find the correct address is to swap between ledger legacy/ledger live or log out and log back in until you are displayed with the correct address.
