Maybe this is just on Firefox Mobile, but for me there is an image of some berries and no text shown for 0.5 seconds, which then gets replaced by a black rectangle, and then text appears that is borderline impossible to read over the black rectangle. The first thing I see is basically broken to the point of uselessness.
Edit: yep, on Chrome Mobile I actually see an animation and stuff seems to work. On Firefox it's borked.
