1. Navigate to https://<your JIRA URL>/secure/admin/SiteDarkFeatures!default.jspa as an Admin
2. Add

   add com.atlassian.portfolio.feedback.FeedbackButton.disabled
   

   in the "Enable dark feature" field

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
