I can't join any raid. Error Message: "rejoin CD not end"

[DKTrue]

V0.18 Release Notes (Focus Quest)

I believe there is a cooldown to join a new group when leaving the old one. I think it is 24 hours. “Rejoin CD not end” translates to “The cooldown to rejoin a new group has not ended yet”, although getting a timer to make it more transparent would be beneficial so this is not seen as a bug.
