I was just simply trying to find out a way to look at all of the support tickets in Zendesk Support, including those that were solved awhile ago.
According to https://support.zendesk.com/hc/en-us/community/posts/115007001967-where-can-I-find-all-my-solved-tickets-, you can just simply use the Advanced Search Filter. However, this doesn't exist in my UI. I'm assuming that this has been changed since that post is from 4 years ago.
