I have won 381468 coins, even then in my city rank, only 377996 coins are shown, I have synchronised coins and also updated the app, even then the problem persists, what should I do now?

If you win some coins because you invite your friend, these coins still hidden but you can use it.

You should contact Hello English by mail and expose your problem. some screenshots are needed to help them sort out your problem quickly. I always do so when I have such a problem. Here is the link: contact@culturealley.com
