Oh wait, I don't think Prime is allowed to connect to Chromecast so I guess it's working normally then. What's missing from the Prime app is the FireTV. Some of these devices use different protocols for discovery (mDNS, DIAL, etc). So I'll need to do more research. VLAN to VLAN was fairly straight forward to get around. My main issue is now with the default isolation policies on the guest VLAN then. If you set the VLAN as guest and flip on guest policies on the wireless network how I've been able to make it sort of work so far is using pre-auth access which I don't want to do because it seems insecure to me. The Routing and Firewall GUI is labeled BETA and seems to ignore everything I define under source and destination.
