Twitter keeps showing a notification about the same Direct Message I've deleted the message from twitter on my computer, and from my phone both using the native twitter app, TweetDeck and the builtin social app. Yet every morning I've got a notice in my status bar and it's the same DM. I've received other DMs since then. Any idea what's going on?
This seems like a bug in one of the apps you use. Best you can do is report it to their developers through the Play store.
