Hi Brandon, I’m currently investigating. The media team is looking at a recent deployment, but I’d also like to rule out a rate limiting issue. To confirm, this appears to affect all users of Tweetium? Is there rate limiting data in the response headers (x-rate-limit-limit, x-rate-limit-remaining, and x-rate-limit-reset) and do they all look ok?
The TweetDeck team is not reporting issues with media upload. Multi-photo is working for me. Who is having an issue with TweetDeck or where did you hear there were issues? That could help track down this as well.
@vic_env, what is the name of your Twitter App? Either that or the app id will be helpful.
