We’ve purchased a “Key Type: Premium (Unlimited Sites/Fonts)” on July 2, 2017 and now that I’m currently updating our site (via a staging environment) the current plugin says:
“You are using old API Key. Please get your replacement key from [here]. You don’t need to pay again. Use your old key as Discount Coupon and it will apply 100% discount. We are sorry for the inconvenience caused.”
However, the old API does not activate any discount on your website. I hope you can help resolve the issue.
Thanks in advance.
