Browsed to https://pkg.go.dev/github.com/gotailwindcss/tailwind?tab=overview - noticed missing license message, added, license, refreshed paged multiple times over the course of several hours.
The documentation, or at least a different error message. Commit reference should be latest commit 18fbd6a
I also would expect some mechanism or instructions linked from somewhere on this page to indicate how to force/request an update if it is not automatic.
It shows message about missing license. License was added about 3 hours ago: https://github.com/gotailwindcss/tailwind/commit/09b9e3febc61bab5ae9f2e92dd336137817cd82f
The commit mentioned, 91cc231, is from 3 days ago.
No indication of how to refresh or otherwise correct the problem (at least that I could see/find).

See the instructions under "Adding a package" on https://go.dev/about. Basically, someone has to go get a version through the proxy for us to eventually see it. We haven't seen 09b... yet.
Thanks and I did get this to work by visiting https://proxy.golang.org/github.com/gotailwindcss/tailwind/@latest and then https://proxy.golang.org/github.com/gotailwindcss/tailwind/@v/18fbd6a.info and then waiting for a bit.
Can I suggest something like the following to make this process more obvious:
My rationale on this is that as a maintainer, the most common thing I would want to do with pkg.go.dev is "update this to the latest", and while now I understand more about the process, it has not been particularly obvious how all this is supposed to work, and specifically what I need to do as a maintainer to get my stuff to show up as quickly as possible.
If you visit the URL path YOUR_MODULE@master, it will 404 with a button to load the latest version.
We can consider putting that button on the overview page.
Closing this issue, since https://pkg.go.dev/github.com/gotailwindcss/tailwind has been updated. I'll open a separate issue for the suggestions in https://github.com/golang/go/issues/41055#issuecomment-682057601.
