Okay, so there are currently two accounts in my Switch system, and I wanted to see if the second account (lovingly named as Guest) has a different save file or something. I soon found out that it did; I was sent to the character creation rather than from where I left it off in Account #1.
Anyway, other details aside, I picked the same starter Pokémon again in this second account rather than a different one, so I'm wondering if there's a way to delete Account #2's save file without affecting Account #1's save file (kinda saved already, so... yeah. Also, the 1st account is already at mid-game, so I'll be bummed if that gets deleted).
