I've been using the FB app since it arrived on iOS. At one point it was a decent app, but it is far from being the gold standard. The last few updates have just introduced more bugs and lag to the experience. Lately I don't even know if I clicked the 'comments and likes' text reliably. You can't tell if you missed the ridiculously small hit target or if it is just taking the usual 3-5 seconds to give you any kind of indication it is doing anything. That's just one example of a frustrating experience, but I consistently have others—zooming and panning pictures randomly closes them, likes sometimes never show up, my own posts won't be visible on the phone, only on the web, etc.
