Prime Rewards not being given

[Cross331]

So as the title says, my monthly Twitch Prime rewards aren't being given despite claiming them.

Now, I've tried the usual advice of unlinking and relinking my account, but I'm still getting nothing, and I've tried this on both my Amazon page and my Twitch Launcher. I'm not sure what's causing is but I was logged into WF at the time I claimed the rewards (Something I usually don't do), so maybe that's causing it or is related? Either way, it's annoying.
