Monitoring - Support for Messenger plugins on Safari 12 has been temporarily disabled by Facebook. This affects web growth tools that use Send to Messenger button or Checkbox Plugin only when the user is using Safari 12.
Facebook team is actively working on addressing this. Unfortunately, they do not have publicly available ETA on this feature.
