Checkout issue: can't change the shipping address because this order has pre-arranged Shipping

HI

Hoping someone can advise on this. When a customer logs in and has used Shoppay in the past, on going to checkout, they automatically get shown this message in place of the delivery address.

A number of my customers are Drop Ship customers, so they are selcting a new address to ship to with each order.

The workaround is to click on Checkout as guest at the bottom, which then allows you to select or add an address.

Any thoughts on how to stop Shoppay for defaulting as the payment method and then stop it forcing a previously loaded address. I suspect it is a bug as if I reload the screen, i can sometimes get around it and find the address selection dropdown.

Any thoughts?

Any resolution to this? I am facing the same issue!
