I was transferring ETH from my Coinbase app to my Ledger Nano S. I used the QR code generated by the Ledger Ethereum Chrome app and it scanned fine. The funds, however, never reached my account. When I checked the email confirmation from Coinbase, it showed the address I sent the ETH to was different from the QR address on my app. Now my ETH is lost and I don't know what to do.
Try to find out what this wallet address is, maybe it's an old wallet of yours that you added on Coinbase weeks ago. If you don't own this wallet then you lost your ETH.
