Can anyone offer any insights into why a user would be unable to manually transition a ticket's status with an error stating they don't have permissions to do it, when they are in the service desk team group, which has transition ticket permissions? I have confirmed that this issue is not isolated to 1 ticket, they seem the same issue on other tickets. I have another user who is in the same role who is able to transition tickets with no issues, the only difference I can see is that this person is also allocated as the project lead. Only thing I can think is that the ticket is not assigned to the user trying to transition it, would that cause the error?
