On one of my machines, I am running the OS X 10.11 Developer Beta 4. I am also running on the Logos Beta Channel and have Logos 6.5 Beta 3 installed.
I have noticed that the Logos Wikipedia Tool is unable to load any wikipedia articles. The tool returns the notification which says "Could not find article on 'Jussive Mood'".
I believe this might be a bug with OS X 10.11 because I am experiencing similar problems in other applications that use a built in web browser. However, I thought it might be valuable to pass my experience along to Faithlife.
