For example, if Table 1 have 3 tickets and I settle one of them, Table 1 will become white (available). How can we check if there are another tickets under the same Table?
This is not default behavior. I just tried it myself. I assigned 3 Tickets to 1 Table. The Table stayed Orange as I Settled each Ticket and remained Orange until the last Ticket was Settled.
Your State flow must be messed up.
Ok, Thank you. I have to find it now
