When loading, and syncing the worlds, the pop up is different and says multiplayer has been disabled, and I can't access my worlds properly. This is my machine and my account. I have uninstalled and reinstalled several times but still the same message. I have made no changes to accounts or settings on my machine so this is strange and frustrating to say the least. Can you sort it please?
Are you able to access your worlds if you open the world settings and disable the "Multiplayer game" option in the Multiplayer tab?
