Pokemon Go just released Pokemon Home connectivity last night for players who reached level 40. An interesting discovery was made: Pokemon with regional forms who's original forms were in Let's Go get assigned the level up moves the original forms had in Let's Go.
This means that if you level up a an alolan Vulpix to level 24 in Go and send it to Home, you'll be the proud owner of an Alolan Vulpix with both Flamethrower and Will o Wisp. Sadly, this can't be used to give Galarian Ponyta Flare Blitz but it does have interesting connotations for Alolan Ninetales.
