With Ledger Nano S and Electrum I can easily sign a message. So the problem is not the HW.
Yes, I know about that. The problem is not with the Hardware Wallet. Ledger Nano can sign and verify messages on Electrum. But there is no feature to sign or verify a message in "Ledger Live". I slightly corrected this statement:
"Ledger live" is what they call the official app (GUI) you have to install on your PC or phone so you can interact with your ledger device (manage accounts, sign messages, voting ...)
