Hi Ifra! Thanks again for the help! It is still not working and I checked to make sure I copied exactly what you had. :/ I'm so sorry I'm not sure what is wrong.
Oops! It appears I got logged out during making the change however when I made the update and saved it successfully I am still getting the same result.
Ahhh! That makes sense. I removed the line you mentioned however the add to conversation is still not available.
We are wanting to use this support center with a partner company of non-agents (end-users) - they need to be able to track their open tickets and add comments on them outside of just their email box.
