I received claimed my first rewards for being a twitch prime owner back in early June. It is now mid July and I haven't received my blue buff or later rewards.
Any assistance in receiving these rewards?
So, in order to get the rewards you have to actively remain a twitch prime owner. As far as I know, the countdown on the days stop if your twitch prime expires. To verify whether your countdown is active just google "lol twitch prime capsules", login and then check it out.
If you need any more help let me know!
Ever vigilant
