As you can see the manual gem reset timer is off. And I can’t manually reset it cause the timer is too long. Not sure if that makes sense.
Makes sense. The timer accounts for both chests
I should be able to pay 1 Gem at this moment but that option is not available. Yes I have tried restarting the game, and phone. It’s just the monster chest. I you can see my raid chest is currently active
The timer is meant for all chests and restricts when you can skip the next time. The next time you can skip is in 1 hour no matter what the timer on your chest says. If you complete the raidchest it will still remain at 1 hour
So in short: Working as intended, not a bug.
