Apparently there is an update available, but the process of getting such an update is broken. When launching the desktop app on the Mac, it says there is an update available, and to "Update Now" which is a button.
The main part of the screen simply says "Loading ...". By looking at the CPU and network activity it is pretty clear the app is sitting there doing nothing or at least very little.
Clicking the button quits the app and then a restart takes you back to the same screen described above with no update installed.
THIS MEANS THE APP IS UNUSABLE IN ITS CURRENT STATE as there is no way to access the rest of the GUI.
I'm running Mojave (10.14.6) on a MacBook Pro if it helps.
Thanks,
Jon
