I'm on tier 2 and the challenge box has not opened up yet and everything still says tier 1 (i marked everything that still says tier 1 with an arrow). When I initially press the prestige button (marked with green, bottom image) it brings me to the tier 1 upgrades section (marked with yellow, top image). I've also noticed the Discord button doesn't do anything. One more thing, in the first release (which I've finished multiple times) there are Male and Female helpers and they fly across the screen. I unlocked the samurai and it doesn't seem to do anything.
