@MojangSupport have owned minecraft since late 2011 tried logging in and it’s saying can only play demo mode #need help
No worries! When only the demo mode is accessible, this means that you're logging in with an account that does not contain a Minecraft profile/username. If you haven't yet, please visit https://help.minecraft.net/hc/en-us/articles/360029643892-Can-only-play-Minecraft-demo-Java-Edition- … for a list of possible solutions. Thanks! ^AS
