How do you change your cover photo on Facebook using the iPhone?

Facebook updated so now there's no button at the bottom I can just click to change it. I can't figure out how to work the new update completely. I hate when apps do this. D;

You can go to m.facebook.com on safari.but the new Facebook update changed stuff like you can't update your profile pic while on the app.so either go to m.facebook.com which is just mobile Facebook or use a computer.

You can update your profile pic by tapping on the photo you want and choosing "set as profile pic" but I can't figure out how to change cover photo either.
