Purging Subdomain Issue

Updated my style.css file - uploaded it to my server, where I can see it’s the proper one

However, it hasn’t yet been reflected on the actual site yet - after 30 min I went into Cloudflare and purged the url but still nothing has taken effect

I have checked in 3 browsers, a private window, and a browser that’s never seen the site.

How long does this purge usually take, and even without it, how long could/should I expect to see my css file updated?

Thanks!

There’s nothing on the status page. When this happens, it’s usually something stuck in server cache. If you add a file, does it show up?

It could just be in server cache.
