I use Feedburner for sending email subscriptions via Mailchimp
It was having problems updating in December. I take two annual breaks in the blog, one mid-December to early January, another in spring. I have just resumed posting but Feedburner did not update yesterday's new blog post yet.
I have gone to the Feedburner page to tell it manually to Refresh, but none of my email subscribers got email yesterday because it did not update itself.
What can I do about this, so that it automatically refreshes itself again? I have written this blog for over ten years and this is the first time I've encountered this problem.
