Yes the commentaries link to the bibles even in parallel mode
check
that the chain icon is still selected
that the commentary has info on that verse it will have a blue i
if these are not the case then esword 11 and higher is broken in this area or is designed to no longer perform this feature
I'm still running 10.4 and tested what you described and it works

Prior to version 11.0.x parallel reading worked fine. Commentaries were updated when a verse would be selected, either by clicking or by using F9 or F12.
In v.11.0.6 clicking does not select a verse. The reference in the status bar showing the current verse is not updated either. Hence no commentaries being updated.
Avoiding clicking by using F9 or F12 does update the current verse reference, so commentaries update too. However, something else is broken here: all the scripture disappears from the reading pane... This must be a bug. Otherwise F9 and F12 need be disabled... However, using F5 or F8 for scrolling a chapter works fine! Scripture is updated (and visible) and the commentaries update.
Hope this clarifies.
