Nit: What is the "VR services check infobar"?  Make sure to write this message
text for a translator who knows nothing about the product and can't see
screenshots, so it has to give context of what the user is doing and what the
infobar is trying to ask them to do.

Done.

Nit: It wasn't immediately clear to me that this gets substituted into the
sentence above, or what the conditions are when users would see this text versus
the below text.  Make sure to spell out these details clearly.

Nit: If this needs to follow a certain capitalization scheme or something, that
needs to be stated explicitly here.

[amp, 2017/02/17 02:52:29]

I initially just had two messages here, but per bauerb@ and
https://material.io/guidelines/components/buttons.html#buttons-style they are
supposed to be capitalized for all translations.

I added a reference in the description.
