What do you usually do when you receive a challenge in a language you are not familiar with?

Answer 1

U can switch off the unfamiliar language... from the settings-->manage weapons...
if u lose a challenge u will lose xp but u will gain some knowledge... It's a steal deal 😎
Good Luck ✌️👍😎

Answer 2

I accept it especially if it's against users with higher xp and hope to get a win. I have nothing to loose anyway.
