It came as a surprise to us, but with Confluence's latest UI Changes (dated January 9th, read here https://confluence.atlassian.com/confcloud/latest-changes-in-confluence-cloud-875410618.html), user experience dropped to a new all-time low. We hardly cannot work with Confluence any longer, your "One sidebar to rule them all" approach only adds more clutter to the UI and the sidebar you need to navigate only shows up when you click into on of the pages.
Confluence is a wiki system, you constantly need to navigate within pages, so the pages sidebar is a MUST for every interaction. Nobody needs a bloated page like this here, it offers no information nor value for my daily tasks: Screen+Shot+2017-03-07+at+1.16.50+pm.png
Moreover, you write:
"There is no opt-out for this feature, but if it is causing you significant disruptions, please let us know at support.atlassian.com and we can explore additional options to assist you."
It would have been a clever move to test this significant UI change with selected users or make it an option, instead you assumed what would be best for all of your users.
How do you plan to solve this, what are our options here?
Best,
Raine
