Update: Tumblr App is working again! 😀 Not sure why it stopped but glad everything is back to normal. 🙂

Yeah, so Tumblr for iOS (not sure about Android) is acting mighty strange right now, refusing to load posts, messages, etcetera.

Tag search appears to be working…
…until you click on it and realize you’re trapped in refresh eternity. 
Other users are whining about it on Twitter right now. 
My Theory: Perhaps something is wrong on the API end preventing the app from connecting (as everything appears to be fine online).
