I cannot find myself on the rankings for Battlegrounds in Hearthstone’s EU server.
This is the reply from your customer service:
Greetings, Jingtong!
Regarding inability to find yourself on the ranking leaderboard.
I checked our knowledge base and there is indeed an issue with the leaderboard, we cannot fix it locally at the moment as we do not have direct access to the game code, our developers are already working on a solution. I would ask you to spend a few minutes of your time to report this error on our forum, this will give our developers more information to fix it as soon as possible https://us.forums.blizzard.com/en/hearthstone/c/bug-report
I understand that this is an unfortunate outcome and, I sincerely hope, that this issue will be fixed as possible, and you’ll return in to the game in no time.
I wish you all the best
Sincerely
GM Nhalishanna
