Community opens right where you left off

Tapping Community used to open a blank page, and you had to pick a channel before you could read anything. Now it drops you straight into a conversation.

The first time, you land in General Discussion.
After that, you land in whichever channel or direct message you were last in.

The full list of channels and direct messages is still on the left. On your phone, tap the back arrow at the top of the chat to see it.
