so in other words you need the sandbox if you want access to what microg would normally provide for you, with the caveat that an account is "optional" for things that "require" one, which in a normal google environment is almost everything and with mirog is pretty much nothing
sounds like microg is the better deal then, if I want to avoid google accounts and Google's snooping
this is useful and good to know, thank you
will help me decide what to go for
