Expected Behavior
If users tap on a hashtag, all messages with that hashtag are displayed in the search results, like in DC-Desktop.
Actual Behavior
DC-Android and DC-iOS don’t have tappable hashtags.
Explanation
I think it makes sense in all chats, but especially in channels. If channel owners use hashtags, subscribers could easily view all messages on a specific topic by tapping the hashtag. This would be particularly useful if channels have existed for a while and therefore have a large number of posts.
