Trying to post a new discussion from the mobile app, and it only gave me a handful of "featured topics" to tag in my discussion. I went to search for the right topic and it said that the topic wasn't found - and yet, I know that they are topics - Ground Cover and Tennessee Gardening - I have even earmarked them in the my subset of "your topics". And yet. They were not presented as an option or able to be found.

Thus I was forced to get on desktop to properly tag the discussion. Seems like something relatively easy to fix, and something that would add massive usability, and help encourage more posting.
