As of 8/13 the paste function is broken in most text entry fields. If I'm on the home feed and click the "Tweet" button in the upper right, pasting works, but it doesn't work in any other context. I can't paste anything (not even text!) in replies, I can't paste anything from any other feed than the top right button on the home feed. The reply/retweet buttons on the home feed are becoming unresponsive, too. I'll have to click them multiple times (or refresh the page entirely) to get them to work.
