I brought the java version TWICE one for each child. it comes with a FREE code to the windows 10 version we tried both o9n windows 10 and it would not let them add each other as friends, because they are child accounts .. and I could not see away to change this.
so then we tried the java version ( ON BOTH ) and it isn't straight forward, maybe something in windows 10 is blocking the server from showing up on its own ? which is annoying because now I am required every time they want to play with each other.
I got them going using the java version ( this is the one we brought, but it came with the windows 10 version and that was preinstalled so they just played that )
I downloaded the java version, and opened to LAN but it never found the server, eventually after messing around a few times I managed to add the server in by IP, but it probably means I will be required each time they want to play because it does not seem totally straight forward ?
I thought the windows 10 verion let them play between xbox , pc and phone ?
but it wouldn't let them add friends ? the whole MS account thing seemed to make it way too hard
