Pending Actions in Twitterrific 5

I'm trying to send a tweet with a picture in Twitterrific 5, but the tweet isn't sent until hours later. What's going on?

Sometimes actions (like sending a tweet with an image) fail to complete because of a slow or absent network connection. In Twitterrific 5, these failed actions get saved to a queue, where the application can try to send them again when a more reliable network connection is available. Because of this, it sometimes can seem like your tweets, favorites, retweets, or other actions aren't getting sent to twitter or are heavily delayed in their delivery. However what's really happening is that those actions originally failed to get sent to Twitter, and it took a while before you were in range of a network that could send all of the necessary information in a timely manner.
