Hello, I downloaded the Yoroi wallet as an add in to the firefox browser. I am using the wallet with a Ledger Nano S. I transferred ADA to the wallet (which worked ok), but it will not let me stake or send the ADA. It brings up a message stating: Something unexpected happened. Please retry. I have re-synced the wallet with the blockchain (which went ok), but still I cannot send or stake my ADA. Does anyone know what I can do to remedy this?

Also it says that the ledger nano s is 'Coming Soon', it has been saying that for nearly a year.... When is this service coming?
