2 parts:
The first would be topics not being properly implicitly tracked. If they were, all of the topics from praise should appear in this step:
It seems like that list is just showing topics with a tracking record of “tracked”, and that’s not working as expected. What would be, would be showing all topics with a tracking record of “tracked”, and all topics which are in a tracked category. (The same would go for watching.)
Furthermore, while this makes sense:
It seems like the same functionality is missing when a user tracks a category. Shouldn’t a tracking record also be created when there is a new post in a topic?
The second would be the appearance of seemingly arbitrary topics in unread when you track a category, (I assume a side effect of changing the tracking state of past topics from regular to tracked), which could be fixed by automatically dismissing those topics from unread.
