× Linking your battle.net and Twitch accounts now gives you tokens for watching! I'd recommend leaving a muted tab open on the Twitch page just to guarantee it, as I'm not 100% sure if being in chat alone is enough give tokens. You can link the accounts here.
To sync video and chat: the FrankerFaceZ Chrome Extension has a built in chat delay feature, I'd recommend 20 or 30 seconds - Quick setup gif (Make sure to turn the delay off when going back to the normal Twitch site!)
No audio? Click the volume icon on the MLG player then again somewhere on the volume slider.

The official streams can be found on Twitch and MLG - Apparently not all games are being streamed on MLG, so please check Twitch to make sure it's not a match exclusive to there!
The schedule can be found here. If you've missed any matches they can be watched here on the Overwatch League site.

Major thanks to Cody for borderline rewriting this whole thing to fix the auto-resizing!
If for some reason you want to give me money to help with the (low) costs to run this: PayPal. Please prioritise spending on OWL skins though!
