I just switched from ios devices to WP8. One problem that's pretty annoying is that all the twitter apps I tied on WP8 do not display replies! Is there any app on the market has this feature?
I tried almost every available twitter app in the store and I can say, that only one can show replies to any tweet - Tweet It! You should select tweet in your timeline and use option "Look for answers". That's only one that I found.
