Access-Unique client ID

Hi there, I’m new to all this and have been playing around with cloudflare access.

I’ve downloaded the WARP client on my machine and have added the WARP client checks unique client ID with a list of the devices I’m using. However, when i try to access the application with the device i get the message " forbidden you don’t have permission to view this" i have also tried this with the serial number instead of the device ID but no luck.

Does anyone know how to resolve this so i can put an access policy on application using the device ID to filter access?
