Sure, a $35 payment can be made for multi site in this case. If to have a new project pending you could purchase a new upgrade for $35 and use that as your multi site key. I’ll make the necessary adjustments on our end. Sure, the license can be used for all of your projects with this theme.
Thanks so much for your support, it’s most appreciated. You’re free to use your latest order number as your multi-site order number. Let me know if anything comes up. All the best 🙂
