Installed via brew cask command and get the following error:

App load error Couldn't load app catalog. Check internet your connection, or try restarting the app.

I am running LuLu which I allowed the process to go through, tried to Retry and Quit but doesn't work for me.

My 2c, I like the logo on the website better than the app icon. The heavy drop shadows make it a bit dated. The website logo is minimal and clean in comparison and would look nice in the dock.
