This is more of an FYI, last week all of a sudden the Twitch login page stopped loading on my test phone (blank page). After some debugging, it turned out to be an SSL error. Turns out there was a bug in Chrome/WebView v53 and Symantec certs.
I noticed most (all?) of your other web assets use Digicert, but api.twitch.tv has a Symantec issued cert.
Given Googles recent stance on Symantec, I thought I’d bring this up here before moving on from this bug.
