samsung s7 facebook app: won't take pix if i tap to focus image. Takes pix if no focus

[AC Question]

The facebook app is weird in my new s7. When I take a pix in the app, if I focus the image, it won't take the picture. If I don't focus, it will take the picture.

No issues w/ instagram or other camera apps.

Web browsing facebook is okay too...

Tried reinstalling the app, but it's locked in adn I can only reinstall the update...
