While trying out WP Beta on my Nexus 9 (5.1.1), I noticed that link preview version 2 is broken. It doesn't come up all the way, and text is cut off in portrait (no text at all in landscape). This is the case currently in the master dev branch as well.
It's fine on my phone (in both portrait and landscape).
Version 1 is fine on both devices, in both orientations. Only Version 2 is affected.
