When I long press my Aripods Pro it just activates Siri, it doesn’t control noise cancellation. Help!

Go to Settings > Bluetooth and then click on the 'i' next to your AirPods and make sure that you have at least one AirPod set to 'Noise Control' under 'Press And Hold AirPods' and then use that AirPod to long press for noise control.

That's strange. Maybe try to un-pair and re-pair the AirPods.

So long pressing either AirPod will take you to Siri even though at least one of them is setup for noise control?
