I can see how to switch off Time Tracking across all boards:
"Select the Jira icon ( , , , or ) > Jira settings > Issues.
Under ISSUE FEATURES, select Time Tracking.
Turn the Enable time tracking option on or off"
However, I am looking to only turn off time tracking for one project, not across all of them.
There must be an easy way to remove the time tracking from a single project... no?
