Thanks for letting us know in here, @prissi74. I forwarded the case to the provider yesterday and got this reply a few hours ago:
We have investigated & found the game round was pending.The game round has been cancelled and the initial stake returned to the player. We can see that the player had winnings of 0.60 before the game round crashed.Below is the Replay URL:https://lon-resource.wimobile.casinarena.com/resource-service/game.html?game=kiss_prt&partnercode=ub...The player should be able to play again now.Please also have the end user clear out cookies and cache before proceeding.
We have added €20 to your account as an apology for the inconvenience. A technical fix was released to prevent the issue from happening again.
