@GimmeTheSuccDad @i_will_be_rb Hey, the issue here is that the notification isn't showing up, but the items are getting delivered. Check your rare-tier items, and you'll have the skins. I checked both your accounts, and you have the skins. 

@Tuinator Hey, they should show up as Night Watch for the Kraber, and Holo Man for Mirage. 

@i_will_be_rb I could swear I saw the skins on your account yesterday, but they're not there when I look today, so I may have made a mistake.

It looks like the Twitch skins for earlier in the season are still present, did anything change with your Twitch Prime membership since those appeared?

It hypothetically could have, but I did check the linked Xbox account before and there were no skins. 

You could try re-linking your twitch account, that's helped with some issues in the past.
