Nordeus are aware of the problem and say they're "working on it", but they don't seem to bother about letting people know about the issue. No change there then really.
Your's isn't the only game that's stuck either. Contact them directly online via Desktop, this should help you. Add a screenshot or two showing the fixtures as well as, if possible an in-game screenshot showing the match being played, or rather not as it'll be stuck on the starting screen no doubt. I've still got one stuck from yesterday afternoon! And it will not clear at all.

As a result we lost the final when we could have won it. I'm not saying we would have but if those games were played then outcome could have been a lot different.
