So where you can see clans war points or points or something like this. I want to know how the rank system for clans work.

Yeah that arrow which is showed in your screen at ranks, i dont have it. I think i have a bug or is a problem.

i dont have it either. also like he said. put your cursor on the rank directly and it show the information you want :P

I put it, but nothing is happening.
