Jar will notify you of client replies on any request.
In order to receive these notifications, you must be either:
1.) Assigned to the request
2.) Be in a group that is assigned to the request
3.) Be a 'follower of the request'
If you meet any of these and still not getting notifications, be sure to check your notifications settings by clicking "notifications" in the dropdown menu and ensuring the preferences you would want are selected.
Please note: Jar will not notify you of internal notes made by teammates if you are not the one assigned to the request.
