I included a "noparse" tag, so that you'd see the code instead of the spoiler tag. You copy&pasted, taking the noparse tag with you, so messed it up. Take out that tag; you only want the spoiler one. Type it out instead of being lazy.
But the app showed the spoiler button! No in the PC there's no spoiler button, but the code itself.
There were these 3 guys. They were named Shutup, Manners and Poop. Manners was picking up Poop from school. Shutup got pulled over by a cop. The cop said "Whats your name sir?" "Shutup." "Whats your name?" "Shutup." "Whats your name?" "Shutup." "Wheres your manners boy?" "Over there picking up Poop."
