First bug is when you do the following:
1- open a friend’s profile
2- click battle
3- click on the small question mark that shows your opponent’s profile (team with troops)
4- click on the X on the top right corner to close the profile and you’ll be back in the fight screen.
5- click the X on the top right corner again and you’ll be back to your friend’s profile and the X there won’t be working when you click it.
The second bug is the same steps above but in step 4, you click battle again and repeat steps 3 and 2 a couple of times and the background will be black and if you click ok then you’ll get stuck in black screen.
i can share videos if this is not clear.
