Hello
I work with a team management project in Jira - Kanban flow. But I have the same issue in company management projects as well.
I want to make Original Estimate field as mandatory (a) when creating a new issue or (b) when transitioning an issue from a TO DO to IN PROGRESS status. I can add the field in the issue layout.

My problems are the following:
1. When I tried to make Original Estimate field mandatory, I didn't find it anywhere. Is is missing from the "Issue -Configuration Fields".
2. When I tried to create a rule for my workflow (start work transition) this field is missing again from the drop down list, but instead I see other custom created fields.
Any ideas?
