Jira Service Desk Management does not support all Confluence native integrations. Due to this limitation, when you link a space to Jira Service Desk Management and try to view a page inside the Knowledge Base section, the Lango Switcher popup cannot be displayed.
If you still want to offer multilingual content to your users on Jira Service DeskManagement, you can add to your Confluence pages the new Lango Switcher Macro.
You can customize the UI of Lango Macro by setting the size and the link types (flags only, text only or both).
For further information visit the Lango Switcher Macro page.
