Good morning,

You must return to all levels to validate the successes.

One thing to note, return to the rooms(aka levels) in order they get first introduced to you. In each room, pause the game and make sure you get the All Collected checkmark for the Tinykins in the mission and task checklist screen of the pause menu.

After doing this in each room, gotta catch em all finally unlocked for me! :)

Still, I wish the devs went back and fixed the tracking for these 4 buggy achievements in an otherwise perfect game!

Gotta Catch 'em All! did not appear to me.

I've lost 3 hours with it, I've probably visited all the rooms, but if it's going to be in the same order, I'm not interested. It's the game developers' fault. If they ultimately want to leave a negative feeling about the game, they've done well.
