In shopware 5.5, I have created a new page in Content>Shop pages. It is called "test page". I assigned it to the group "General".
In link address field I entered https://www.thefishsociety.co.uk/test-page/
I cleared the cache.
But when I go to the above URL, I get "Sorry, the page you are looking for cannot be found"
How do I set URL for my new page?
