Xp levels are not going up whether I'm killing mobs or mining coal ect. Sometimes they might go up but very rare. I've tried killing with different swords & axes plus mining with different pickaxes. Both enchanted and not, iron and diamond. I'm only level 9 due to enchanting so mining a full stack of coal should of a least moved my xp bar. I'm playing on xbox one multiplayer and their xp levels aren't going up properly either.
