Now that (partial) media queries/CSS support has rolled out to the Gmail app for Android and iOS, has anyone had success getting this to work on Android 5x (Lollipop) phones? I happened to be testing a few emails on a Samsung Galaxy Grand Prime 9940 with Android 5.1.1 installed. The email wouldn't rescale to the screen as expected via the viewport meta tag when I removed all media queries/css from the <head>.
