Hello Vincent,
Extension was updated. Duplicate zones issue was fixed.
Thank you for your request. We want to implement sync NS records so Plesk zone will content Amazon NS records. Will it useful for you or you want to use common delegation set?
Hello,
Unfortunately, this issue cannot be fixed in such manner because SSL certificate validation is performed before redirection. Even if you set up redirection to correct address, your customers will still see SSL certificate warning.
In short, you can change this behavior if it's not applicable for you. There is article about how it works in Plesk: https://devblog.plesk.com/2013/12/about-plesk-url-or-telling-customers-the-right-address-to-go-to/
