Hi everyone ! I allow myself to write here because there is no other way to solve my problem ... at the release of pokémon home, I transferred my melmetal shiny from let's go to sword and shield; I didn't know I couldn't teach him earthquake in pokémon SwSh :( I can't modify the pokémon myself via PkHex because I don't have a hacked switch. If someone could modify my melmetal to add the attack I would be very grateful :) thank you in advance !

Same problem, Sky form is in Bank dex, but not in Home, that's a glitch. Like with the many challenges that are broken for some people ( like unown, vivillon ... ). There's no fix actually, if the above instruction doesn't work for you, you're doomed, like me, waiting for a fix...
