I'm seeing now that I have some of my 2.3.2 sites that aren't having this issue and others that are. All of the same addons/versions so comparing anything else that might be different. I've tried several browsers and devices - chrome, safari, mac, ios, etc.. to no avail.
Here is the browser console error...
