Hi there, @user25237 and welcome to the Community 
Thank you for the feedback!
I’ve checked your widget and see that your post was published 2 days ago. Since the cache time is 48 hours, the widget worked as expected and the post appeared today.
However, I completely understand your point that it would be great to pull new posts even faster. At the moment, it’s impossible to reduce the cache time further, but if anything changes, we’ll update you here right away
