On desktop we show categories and topics separately, but on mobile we show categories with topics, combined. Keeping that in mind, it is this line that causes the bug:

> <https://github.com/discourse/discourse/blob/main/app/models/category_list.rb#L147>

`c.displayable_topics.blank?` is always true on desktop because we load topics separately so `displayable_topics` is always blank. On mobile, it is true only if there are really no topics in that category.

We have two solutions here:

- show uncategorized if there is at least a topic, no matter the value of ‘allow uncategorized topics’ setting

- hide uncategorized even if there is a topic, if ‘allow uncategorized topics’ is false

The second solution is easier to implement because it means we simply remove the second part of the condition.
