UPDATE: Support for Structured/Managed Navigation enabled on Modern Pages in Classic Team Sites

The structural navigation is now broken for me. It worked for a couple of days and now the submenu in the structural navigation opens the Site above the Site I have set. Editing at "quicklinks.aspx" or "AreaNavigationSettings.aspx" doesn't help. The links are correct and it still opens the Site above. Adding new items also results in the same behavior. The order for both the structural and global navigation was also randomized on it's own today. Also tried adding a sub menu in the global nav and the items all open blank pages. Don't even want to fix the global nav anymore. Would be nice if something as basic as navigation would simply work. Regret having adviced the customer to make use of the modern pages. It's kind of hard to explain to a customer that you had to spend more than a day to fix something as basic as the navigation. 

edit- just noticed that you mentioned that the fix should be deployed by the end of this week in the other post. Have advised the customer to wait and create a ticket if it's still not working after Friday.
