Not really sure if this is a bug or intentional.
if ‘top menu’ setting is set to ‘categories’ first, clicking the site logo does not refresh the page content.
This can be tested here on meta by clicking the view buttons along the top of the page. click latest twice, content reloads. click categories twice. second click has no effect. (only the categories view is affected) My own discourse instance is set to categories as default and a user reported this behavior on mobile.
I understand if this is intentional as the categories list should not change much. But, the recent combined ‘categories/latest’ view should have this behavior available.
Hopefully I explained it well enough.
