What on earth is going on? A few minutes ago I had a glitchy but usuable Facebook app. Searches had stopped working and I was being prompted to update. 2 mins later, update installed, and I now have a completely unusable app that fails to load pages, freezes or tells me, "this page isn't available at the moment". How is it possible that an app gets WORSE with every update? Now having to open FB on a mobile web page. Absolutely useless!
