When the field crew is doing work in the field, they have the ability to add an internal note to the work order.
This internal note will be updated to the work order, and the field crew can choose whom to send the internal note to.
The chosen user will get an email indicating they received a note:
Clicking on View Note, they will be taken to Method where they can view the Internal Notes.
NOTE: The App they view it in will be dependent on the recipient's permissions. If they have permissions to the Work Orders app, they will see it in Work Orders. If they have permissions to only the Field Crew app, they will see it in Field Crew.
Selecting a note will allow you to view it as well as create a new note in response.
