Yes,
1. **Make the post longer.** Add at least 60 words of real text to the post body (a short paragraph or two), then update it in the Studio. A one-line post will be held back again. Write it as something you'd be happy for Google to see, since it goes on your live site.
2. **Tell me when you've updated it, don't wait for the timer.** GitHub has accepted the hourly timer (it's switched on and points at the right branch), but it has now skipped both its 06:17 and 07:17 UTC slots. That's a known GitHub delay with brand-new timers, but I haven't seen it fire yet. When you say "done", I'll start the sync by hand and follow it until your post is live, about 10–20 minutes.
If the timer still hasn't fired by the next slot, I'll set up a more reliable trigger, which would need you or Joseph to paste one key into Cloudflare.
