Question: What do I do if I get the following error message Alert "1-Setting both Original and Remaining Estimate is not supported in Legacy Mode."?
If you receive that error, you should perform one of the following:
Check with the Jira admin to disable legacy mode from the Jira configuration.
Set a value for "Original estimation".
Check with the Jira admin to remove the "Original estimate" and "Remaining estimate" from the Create screen.
