We utilize an F5 portal to allow our vendors access to our internal Jira instance. We recently upgraded from 8.5.6 to 8.20.1. When our vendors access Jira through the portal, they see the header and menus but the menu dropdowns don't work. They can search and view issues but editing does not work. Is anyone familiar with this setup? My assumption at this point is that there was some configuration change in Jira that is causing this to no longer work appropriately. I've been digging through release notes to try to find what may have changed with no success. Is anyone aware of any changes that could have impacted this type of setup?
