PatchedEverwing Facebook Messenger Hack

I get to the step where you change values and it won't let me type anything in there. Why is that?

Edit: I'm on Chrome as well. I open in a new tab and I can't find it where it lets you change value or anything.

Doesnt work.
Chrome now displays {"message": "Invalid argument: coin", "error": true}

This has been patched

This method doesn't work for me. The global link won't pop up... any suggestions?

I can't get this hack to work! The global option isn't appearing anywhere! What am I doing wrong?

Going to see this
