I have a problem with the Balancion

I have a problem with the Balance I just completed the diarion challenge of this event and it doesn’t let me claim either of the two rewards. please how can administrators solve this

I have the exact same problem with day 7 reward. The whole screen is almost unresponsive. The only thing that works is spam tapping on the back button and “enter trial,” which gives the standard error of come back tomarrow.

Sometime the game freeze.have you tried closing the app and opening it again?
