How to Use Your Twitch Prime Sub and Link Amazon with Twitch for Prime
Step 1 Go To: https://gaming.amazon.com/links/twitch/manage
Sign in with Twitch and link, your Twitch account to Prime Gaming.
this will link your Amazon Prime with Twitch Prime (now prime gaming)
You should see your Twitch account and the unlink button on right when you are linked.
Now go to the channel you want to give your Twitch Prime Sub to like DragonBloggers Twitch for example
if the channel is offline you have to click on “Chat” to get the subscribe area to be visible, then click the sub button.
you will see a new checkbox that says “Use Prime Sub” but it only shows up if you linked
Check mark and then the price goes away and you use your PRIME SUB. Prime sub will not auto-renew so you have to come back every month and re-sub or use it on another channel you want to support. Your prime sub costs you nothing to use and helps provide a little free monetary support to your favorite streamer, so leverage it to thank your favorite Twitch entertainers. If you are on a mobile phone using the Twitch mobile app you can’t seem to use Twitch Prime Sub inside the mobile app, instead you have to navigate on your phone browser to https://www.twitch.tv/subs/channelname like https://www.twitch.tv/subs/dragonbloggers
and it should give you the option there.
