If I turn Guest access on I cannot get into a MyBookLive, which apparently needs "guest" as the username and no password. Turning off Guest Access in RuneAudio release version: 0.4 (build: beta-20160313) on a RaspberryPi2 (08) and entering "guest" as user name with no password grants access.
The "Guest access Off" button does not apply to all circumstances, although it is clearly explained that no user name or password will be given. Perhaps this can be made clearer in a future release?
