I am trying to enter the 1st of December 2026 into a Confluence page. However despite all my browser and Confluence settings being set to DD/MM/YYYY its still interpreting the text I type as American format i.e. NOT the format that the rest of the world uses.

Why ?
And ironic given Atlassian is an AUSTRALIAN company ... that they don't setup with DD/MM/YYYY 'out of the box' for Australia or the Rest of the world who also use DD/MM/YYYY
