Condemn Tumblr App to Oblivion~!

It's been so frustrating using the Tumblr app on my iPhone 4S. I don't know why but every time I tried to post something to my Tumblr blog via the app, the posts always never come up when I checked back online. This happened so many times that it's getting really ridiculous. Gawd! I'm so pissed with the app that I deleted it from my phone. Now I only stick to using the web to update stuffs on my Tumblr blog. What a lousy app! Tch.
