Why can't I 'Post' under 'UK Topics'

When I select ‘UK Topics’ in Filters the New Post button doesn’t work - I’m in the UK!

Hi @user12385. When you navigate to the Categories section, you should see the UK Topics header where you can select the category you want to post in. After selecting the category, there will be a “+New Topic” button in the top right. If you don’t see that, please share a screenshot of what you see so I can better assist.
