We have released a minor bug fix update in version 4.3.1 of the app.
On Who to search? screen in the list of pages if you tap on the (i) icon to see the page profile screen, the app used to crash. This is due to a change in Facebook API specification. We updated the app for that change.
On Options screen many buttons in Information section would show a page with “Content Not Found” error. This is due to the fact that we launched the new website. This is now fixed and those buttons now display the same content as the website.
