Thanks much, Waldo. I just sent an email as you suggested. Hopefully I'll get a quick and direct reply.
In the meantime, I think you might actually be able to clarify something for me, if you don't mind...
You suggested I follow the instructions for setting up a custom domain -- but that requires that my client purchase a hosting package with Webflow. But she already has a great deal with her current hosting company? So is it possible to do a re-direct without having to purchase Webflow's hosting/custom domain?

Thanks again. I didn't have this issue when I built some webflow sites last year.
