When editing events, there is a convenient View on Frontend link on the backend of every event that allows admins to easily access to the frontend view of the event. Keep in mind this link opens the frontend view of the event in a new tab.
Admins are welcome to edit the event on the frontend (it is encouraged). Once edits are made on the frontend and saved, if the backend tab for the event is still open admins must first refresh the original backend tab for those changes to appear.
If admins save the backend tab without first refreshing the backend tab, the frontend changes will be overwritten.
