I have attempted to follow this thrice now. I've uninstalled facebook, ive gone back and changed clothes in the vanilla app too - but nothing works. It just doesn't give me the option to update later, therefore i don't even get to log into facebook.
I've done this step by step. I've tried it again and again, with and without restarting my phone, but it never worked. I'm positive something I'm doing is wrong or it just doesn't work anymore, but even following this guide to a T didn't help.
Might go back to vanilla for a bit, I don't really want to start over yet again, but i seems I may have to. Before anyone else loses hours over this - I'm not sure this works. It might for others, but it hasn't worked for me so far.
