if you had made some points in the league before the problem that would be lost unfortunately but its better than nothing

When will this be fixed?
Staff are working on a process to identify the impacted divisions and handle them. However, if you're not in a place to promote, leaving leagues, rejoining, and playing a game should place you in a new division.

You have to leave the league anda join again, when play and win a one game, it's ready
Ya. I just did that experiment and I am in though I am not interested about this league.
It took 30 minutes to reach 3rd position.

We should really all be just glad and grateful that we can sit and chill playing chess whatever league, right now some people don't have that luxury.
