Plan Transfer - More Complicated

I’m having trouble with
transferring my Premium Plan from one Wix site to another Wix site within the same Wix Account.

Working in
Wix Studio

What I’m trying to do
I have two websites within the same Wix Account - I’ve purchased a Premium Plan for one of those two websites. I’m trying to transfer my Premium Plan from one site to the other site, and every time I do, I get an error message saying “We’re unable to transfer… because of a technical issue on our end, please try again in a few minutes.”

What I’ve tried so far
I’ve tried two separate ways to transfer my Premium Plan from one site to the other within my Wix account. Through Billing & Subscriptions → Domains → Assign, and just through the dashboard.

I’m using a Google Chrome browser. I’ve cleared my cache/cookies and I’ve tried transferring it on Safari browser with no success.

I’ve also spoken to a Customer Care rep at Wix and they told me that I would have to purchase a second Premium Plan, essentially I would be paying double the fee even though I only want one Plan and one website live. It’s Wix’s fault it’s not working and the error message I’m getting proves that!

Extra context
Anyone know a work-around without starting from scratch to build my website on the Premium Plan? It’s taken my hours to build this. Thank you for any advice!

So this didnt work ?
