New Widgets not available

They’re in the Appearance > Widgets menu – not in any of the Jetpack settings. I’m on v4.9 and I can see all three new widgets.

At Jetpack.com I received the following solution:

Go to this page in your dashboard, and make sure the Extra Sidebar Widgets module is active on your site: https://yoursite.com/wp-admin/admin.php?page=jetpack_modules

After that they show up where they should.
