Opera version 72.0.3815.148 and I can't get it to work (neither from the address bar, nor from bookmarks, nor from speeddial). Even by deleting the folder ...\AppData\Roaming\Opera Software and installing from scratch is the only extension that still doesn't work. On the facebook page, the "Switch to old layout" button (and the subsequent OK on the 48 O'clock warning) simply updates the page and the design does not change.
