IMPORTANT FOR LEDGER ACCOUNTS: You can allow a Ledger account on all chains only if it has been added directly on the Polkadot-JS UI. Ledger accounts added in the Polkadot extension cannot be used on all chains. 

However, it is strongly recommended that you use a Ledger account only on one network, otherwise you may lose access to your funds.
