I read somewhere online that both Windows 10 Minecraft and the Mojang version can play together on Realms. Is that true or is there no way for the two versions to be compatible?
windows 10 edition can not cross play with the java version
There is a project on GitHub called DragonetMC
Supposedly its goal is to allow Bedrock (Win 10) clients to connect to Java servers. Not sure how far along is that project though.
