You can sync stage from prod using GoDaddy’s dashboard. Go to Managed WordPress > Settings > "Staging Site" Actions > Sync Sites.
Select "Pull production to staging" and check "Overwrite content" and hit the Sync button.
You’ll get an in-progress message that reads like it’s syncing stage > prod. The message doesn’t seem to automatically clear itself in the browser after the process completes. Does take a few minutes to complete.
