I recently bought a Amazon Fire HD8. When opening a Facebook Marketplace thumbnail, the full screen image is cropped at left and right margin. When uninstalled, and then reinstall Facebook, the thumbnails start off displaying full screen, as they should. Within a few minutes, the left and right margins are cropped. Is there a fix? Thanks,
