Thanks for the context, am I understanding right that Webflow isn't letting you route that subpath without paying the obscene amount of money, so you put a proxy in front (Cloudflare) instead.

I know this is a pretty silly suggestion and an attrocious hack, but with webflow already at the root, would a full page iframe on /xxxxxxx work?

And clearly going to just `app.domain.etc` was a non-starter?
