Warn: Not Whitelisted Issue

cards

#1

I’m trying to setup cards for https://mobileaccessories.co.uk when I run it through the validator it says the domain isn’t whitelisted.

Can someone point me in the right direction to get this domain whitelisted?

Thanks

Are you sure you have Cards markup implemented correctly?
