@SashaMC 

Thank you for the response. I tried your suggestions, details as follows:

Reset the app's data (Help > Reset App Data)

No change in behavior

Clean boot the app (i.e. hold shift while opening it)

No change in behavior

Reinstall the app and check.

Well, we made some progress, although now in the completely wrong direction. When I downloaded a fresh version of the app and installed it, OSX refuses to open it because it cannot verify the download. So now I can't use the app at all. This includes context clicking the app and selecting "open" which will often get you around the Apple security checks.

I guess at this point I would request an escalation of the issue since the newest version app is non-functional, at least on my laptop.
