The updates for this shit are always slow as hell, and now with champions it feels like they got the perfect excuse to make them even slower, it really shouldn’t take half a fucking year to just add a few png to a collection app specially in cases where there’s no new pokemon, all it should take to make FRLG compatible is a tiny GBA icon and a little text With champions now they’ll intentionally take even longer to update to force people into recruiting new pokemon in champions instead of just transfering from their home boxes
They’re slow to integrate new games to control how people play them, nothing to do with work to do. That’s simple and probably ready to go from release. These games are all designed to be able to move stuff back and forth from the get go.
