Language selection module 8.x.2.3. I have 2 languages enabled, each setup with it's own url /en & /fr. The detection and selection has the correct order
URL > Cookie > Language Selection page > Selected Language
The standalone template has been set and the html--language-selection.html.twig page created from html.html.twig.
When I visit the site www.mysite.com/language-selection it immediately redirects to the front page mysite.com/en.
I have followed the minimal instructions in the readme and can't problem solve. I have cleared cache and doing most of my testing in incognito so cookies shouldn't be an issue. How do I take control of the language selection page, so that users can select their preferred language, and the administrator can properly test the module.
Any guidance would be appreciated.
