SubscriptionId on links

Hello Paul,

Thanks for this very helpful plugin!

In the latest update, I’m having the variable “SubscriptionId” added to all generated links (at the end), even if I haven’t entered the AWS keys (I’ve left these fields blank in the setup page).

Here is an example:

…&creativeASIN=xxxxxxx&SubscriptionId=%PUB_KEY%

Any idea about how I can remove this variable?

Thank you very much!
