I also lost my Messenger and Articles icons after the update to RC9. 

I migrated from Dolphin to UNA with a paid license. I do not see Font Awesome Pro available except for an additional fee. Could I have logged in with the wrong profile? None of my profiles seem to allow for a free download or update. Would that make any difference which profile I used?

Yes, I am aware that Articles is a 3rd party module. If that is a factor. 

Thank you.
