I installed the latest Version of Max2Play (from the image provided on your website) – the image is 2 weeks old at the most. I did the Kodi upgrade from the upgrade button, not by providing an URL.
I did a fresh installation – installed the image, configured the Sqeezebox server, which runs nice and smooth (including radio streams), then upraded Kodi – same result. I can play local music, but anything that requires a connection to the internet fails.
