Hi @Gria, have the key in your inventory, but don’t hold it. Stand close to the Temple Door, and then tap on the door. It should unlock.So I just defeated Plantera on the mobile version of Terraria and I got the temple key. But when I went to the Temple to open it, the door would not open. I tired everything. Shutting down my phone, restarting it, etc. But it still wouldn’t open
