The "submit" button on our KB articals, knowledge feedback is gone so users cant submit feedback:

Can you give us some more information? When did this happen? What happened right before that? Did you upgrade or patch? Have you checked the sys_update_xml table to see what happened around the time it disappeared?

Hello im not sure when it went missing. I have seen videos of people online that are showing off knowledge feedback and i also see them not having it, example here you can see theres no submit button:

We are having the same issue.  Do not know when it disappeared and have not found a way to get it back. I know we did not make any changes to knowledge article views.  We are on Vancouver, I am wondering if this went away following the upgrade?
