I am quite shocked after reading the comments. There are some people who believe Israel are the victims, after all what Israel did this past few months.

I don't know what caused it either. Maybe because I updated the app from the previous version?

Well, I have uninstalled the app and reinstalled it. The buttons are appearing just fine now.

Yes, 0.2.0 from Google play. When I said the buttons didn't appear, I meant in the feed, when I enter to see the comments the buttons are there.
