Again, just to be very clear, the bets is under review by their game provider, not by them. The speed of the official reply with verdict is not on their hand. I hope you can understand this concept as I can't find any other way to explain it better than I already did.
That said, I am in touch with someone from Shuffle for a matter. I'll get them to look into it to see if the provider already greenlighted the transaction and that good-to-go message accidentally slipped and drowned by other messages. But I believe that's the extent of what I and my contact at Shuffle can do.
Any update you got from shuffle team? Why it’s taking too long time to solve it
If I may repeat again, the investigation is done by the provider and not by Shuffle, the length of the investigation needed is completely at the hand of the provider, not the casino.
That said, I apologized that I forgot to nudge my contact for an update in case of an oversight. I had an oversight of my own. I'll nudge them now, though they're quite likely already off-hour. Hopefully they'll be able to update me when morning come.
