Summary of issue: The main menu functions don't work after canceling the event option.
Device: Xiaomi Redmi 3S Prime
OS: MIUI 10 based in Android 6.0.1
App Version: 2.31.2
I just checked and this, and it also affects iOS:
Device: Apple iPhone X
OS: iOs 12.4.1
App version: 2.31.2
Steps to replicate:
1) Go to main menu
2) tap 'events' and wait for the events page to load
3) tap 'done' to return to the game
4) tap any button (except X), the button animation plays but nothing else happens.
Workround: Tap X to leave the main menu, then tap the main menu button to return, buttons will start working again.
