This is just going to take some time for certain apps. Companies like Facebook are huge bureaucracies now, they have software roadmaps that extend way out into the future and any updates go through extensive QA before release. Also, catering to Apple might not be at the top of their priority list. It's not like customers are going to run to a competing social media app because they didn't update their software soon enough. It's Facebook.
I'm glad Apple set a deadline. Otherwise some may never update.
