Multiple ways of expanding/collapsing lists

There are a few expand/collapse functions.....

Expand/Collapse all - just double click the Workflowy icon
Expand/Collape all under one parent item - zoom in on the parent, then double click on the parent text
Expand Collapse level by level, under one parent - zoom in on the parent, click on the name of the zoomed item (at the top in big font) and then using the ctrl+up/down shortcuts while focused on that item. It will expand or collapse all items below the zoomed item to the same level.

The expand / collapse function seems not to be working as intended.

When I double-click on the workflowy logo, it collapses all, but does not expand when I double click it again
When I double-click on the parent text, it does not collapse or expand all
Also the single level wise expand/collapse by clicking the parent text once is not working.

I am using the web version on the latest version of Chrome browser on my Windows laptop.

This is a terribly useful feature and I miss being able to use it. Would be happy to learn if I am using this in the wrong manner.
