A Twitter representative had earlier said that the company was investigating issues with TweetDeck, primarily used by journalists, media houses and other content creators for monitoring tweets from multiple Twitter accounts.We've been experiencing outages across Twitter and TweetDeck. You might have had trouble Tweeting, getting notifications, or viewing DMs. We're currently working on a fix, and should be back to normal soon.
