I saw this other question get posted:
https://mmmcommerce.com/F...-working-on-checkout how has this gone, did anything get added to a release?
we may start looking into it and if needed to help speed it up, are looking for others affected by the issue who may want to help pitch in with cost of dev. If so, reach out and talk with you about it.
if not, sit tight... i'm sure someone will get to this soon!
