I tried to install this on my Mac Mini this morning, I removed the old Kodi install and installed v16.0 but the Blue Moon directory wasn't appearing, I had a couple of goes at this and then gave up. I then tried on my Android T8 TV box and had the same problem. I was beginning to think that it was something to do with me using a VPN from behind the Great Firewall but I haven't had any problems in the past, I'm actually glad to see that it's an issue with the updated version and not my stuff!
I'll give it another try at weekend if you have sorted the problem out by then.
