Optimize Press replied on this thread to me...
Hello Steve,
Lourdes here. Thank you for the email.
OP3 doesn't have the upload template feature at the moment. It uses cloud template library which is accessible once you have OP3 installed and activated to your site.
If you do have a page created using OP3 at another website, you may save the template to your personal template cloud library. Doing so will make the template available to any of your sites using the same OP3 account. You may find the details here: using and sharing in the templates cloud
I hope this helps. If you have further queries or concerns, please let us know.
Kindest regards,
Lourdes
