Suddenly, I am getting an error when I try to change the status of tickets to In Progress: "Please enter Original Estimate."
Time tracking has not been required on this project for years and suddenly, out of nowhere, it is. So... I went to field configuration for Time tracking and it was required but hidden. I made it optional and removed it from all screens. Same error.
Then I went to settings > Issue Features > Time Tracking to disable it completely per these instructions: https://confluence.atlassian.com/adminjiraserver073/configuring-time-tracking-861253946.html?_ga=2.203584528.1073167183.1580945979-2121314446.1548960953 but there is no "Deactivate" button!
I don't want time tracking at all. Don't need it and it has been disabled/hidden on this project for years. Don't know what changed to suddenly make this a problem but I need to disable it. What do it do???
