Would like old app back! – Ultradex Free for Pokedex Pokemon Sun & Moon Games Review

Removing the older generations of Pokémon makes this app useless for me. Many of us are still playing classic incarnations of these games. Please make the older app available or at least tell me how to get the old version back.
