Nothing will post to the feed!

I have been trying to share some screenshots, all I get is a loading circle, then it sends me back to the feed like nothing happened!

Recreate:

-Click 'Feed' in the menu

-Click 'New Post'

-Choose a screenshot

-Click 'Share'

There will be a loading icon - it will then load back to the feed, with no new posts!

**I've tried more than 10 different images, trying to share a new post each time!  Nothing posts on the feed! I also tried with and without using text in the 'What are you up to?' pane but it has no affect!

Nothing posts to the feed!
