Despite what this image may tell you, your trainer profile/ID isn't just tracking the shinies you've battled. It also counts any evolutions and eggs that happen to be shiny. The question is, does this operate like SwSh's shiny tracker that it identifies one per species, or does it count duplicates? Does it track other shinies you've seen other people bring to raids? Does it track the shinies that have spawned but passed by?
Haven't had the luck yet to test any of these hypotheticals so I'd appreciate any help.
