The popovers do not work at all. Trying to use the right toolbar - clicking on the popover icon (in write mode and input selected) - nothing happens. Clicking on the first tools icon also does nothing.
If the Notations toolbox is set to “popovers” (the keyboard icon) then the buttons open popovers.
However, most of the time you’ll need to have first selected something in the music - to tell Dorico where to open the popover.
If that’s not working for you, can you say a bit more about the exact steps you’re following and your setup - do you have multiple monitors, for example?
Could you share a video showing what you’re doing in your screen? Are you just clicking the popover button at the top, or are you then clicking the button in the toolbox that corresponds to the popover you want to open?
What should normally happen (and happens on my system with Dorico Pro) is selecting the note and clicking a popover button on the right causes the dynamics popover to appear directly above the note.
What happens when you select the note and press Shift-D for the dynamics popover - does the popover appear then?
(In asking that I’m trying to ascertain if it is only an issue with the popover toolbar on the right or whether it also happens when you call up the same popover the normal way with the hotkey)
