Hi Tony, I apologise for the wait as our office are normally closed on weekends.
Although we did release a post on our blog regarding the new requirement, and it was also mentioned as a Notice in the previous core version of our plugin, you're right in that we haven't yet displayed the requirement on the product pages. Having said that, the post explains why we took such a decision.
We will be working on improving our website very soon, and in the mean time we will be providing you with the refund for your purchase. We will be in touch very soon through your premium support ticket in order to process the refund.
We apologise for the inconvenience.
