Having this bug since the start of Season 17. Every time I press the PVP button, game is showing the PVP reward ladder and all the rewards I got from my rating. But when I press the ‘Claim’ button - game crashes and I need to close the app and open it again.
May be this problem occurred due to entering a PVP match on last seconds of the season.
What has changed? I have the same error, how can I fix it?
