QN90B - Firestick Max 4K Wont play UHD?

[iamblakey]

I have a QN90B and when I try to use the Firestick 4k MAX it says there is no HDCP 2.2? I thought all 4 ports are HDCP 2.2?

Why would this be happening?

Amazon support have said it must be an error or issue with the TV

Plug your firestick into a another TV or monitor and update the firestick. My guess is the firestick needs a update.
