@dan - The issue where the sub-menu’s were not showing that were introduced in Version 7.1.0 (18110b) seem to have been fixed in Version 7.1.0 (18121b).
I tested on many projects with sub pages and they all seem to work just fine in this latest beta.
A word of warning though, I was having issues easier with export and publish… If you get a chance can you test on your own projects and let us know how you get on.
@dan - What I have experienced with this latest beta is that when I publish the entire project the publishing hangs and never really publishes. It just gets stuck in export mode.
But is I right click on a page from the left most sidebar (where all the pages are listed) and select “Publish Page” then it can publish the page (including sub-pages) as expected.
