Toolbar plugins not working on Mac, but do on Android

Plugins like Editing Toolbar and Note Toolbar don’t work on my Mac, but are available to me on Android. I just installed Note Toolbar just to see if it would work. It doesn’t. It seems to me that Editing TB used to work on Mac for me. But maybe I’m remembering incorrectly as I generally just do Markdown and such manually. Do these plugins only work on mobile? Or is there some setting I’m missing? Excuse me if I’m missing something obvious.

I’ve tried enabling and disabling some things. I use PopClip on the Mac, which instantiates a popup menu when I select text. Disabling that doesn’t help. I’ve restarted Obsidian after making various settings changes within Editing Toolbar, to no avail. I’ve tried using the Default theme instead of my usual Shimmering Focus and Cupertino, but that has no effect either. Searching this forum hasn’t shown me anything parallel to work with.
