Wordpress 5.2.2
Pro 2.5.5
WooCommerce 3.6.4
With the above setup WP Dashboard > Settings > Customize is broken. This is a problem because WooCommerce moved the Store Announcement feature to this section. This is a problem if you’re using Pro’s default store template, because you can’t use the Store Announcement feature.
Until this is fixed you’ll have to make a custom store page and post your announcements there.
