Question

the mobile app for os sucks. no notifications, chatrooms, or @tagging!

Answer 1

Also, no deleting responses, bumping questions, or closing them.

Answer 2

tagging does show up, just not through the comments you see
so I guess if you memorized that person's complicated user name.... ;P
and you're right about all of that
and some good stuff about that is that there is no "one question at a time" limit
and you can use it without appearing online (so it's like going afk)

Answer 3

yeah it's reaaally dumb :c
