Twitter I don't know what you did to your app, but ever since a recent update it will scroll all the way back up to the top of a thread after I ) read a comment and try to go back 2) the screen shuts off and I turn it back on 3) switch to another app and switch back. This is a huge problem when I'm trying to read a tweet that has hundreds or thousands of comments and I have to keep scrolling back down to find the one I left off at. Please fix this.
