This tweet lacks a lot of context. In what app was the screenshot taken? - for example netflix does this for all screenshots inside their app.

Do other screenshots look blank as well? - screenshot feature could be broken, idk lol

What version of ios does she use? - I heard there are a lot of bugs in the current beta

I don'l like apple, however this is next level. Just tweeted something, tagged a lot of famous people for technical support and left angry...
