I have a custom activity entity in solution. For this custom entity I have defined and enabled status transitions. It is going right for installations except one installation. For installation that it is not working in, status transitions are disabled. I have asked customer to enable status transitions but he couldn't do so.
He says that he is able to enable status transitions. But after saving it when he closes form and opens again then he finds that "Enable Status Reason Transition" check box is unchecked.
He has installed managed solution (using AppSource). Status Code field is unmanaged of activity entity.
How can he enable status transitions?
Any Solution or help is highly appreciated.
