Netherite upgrades not working on Smithing table

Both myself on Xbox One and my friend who plays on Windows 10 version are finding that we CANNOT get either a plain or an enchanted diamond pickaxe to upgrade to Netherite. We attempted both the Crafting table method and the Smithing table. This is rather extremely furstrating! Please help.
