Doesn’t work

I can’t link my flickr account with Pixfeed, only stream interesting photos. I launch the app, then I click My Photostream tab. It asks me to connect my Flickr account.
Then sometimes an embedded browser pop-ups, sometimes pop-ups a white (useless) window. When the browser pop-ups it directs me to yahoo and ask me to login with my username + password. Fine. Then Flickr says “invalid oauth protocol”. So I can browse my photos in the small browser, but not into the app. To quit the app I need to force exit.
Please, fix it. App design is wonderful.
