Same problem here. I have installed the new plugin, deactivated everything, reactivated and nothing has changed: no “shortcode” button on visual editor.
My review to this:
I’ve installed a TinyMCE Advanced plugin, and copied a shortcode from Docs to a page. Then, the “4” button was there in Visual Editor. I’ve deactivated the TinyMCE Advanced plugin and the button was there….
I found it on “Docs”.
Any workaround or guide to manually create shortcodes while we wait for the new theme version?
so, no problem at all now…. But it was weird.
