Sent a codemoji and it resolved in a 404

Worked properly when I tried again on Firefox.

When I tried again in safari it didn't 404, but the decifered message was way off and nonsense

Yeah, seen a high number of 404s in GA. @acabunoc do you think it might have been special characters in your message?

[abbycabs]

No, my message was something simple and 'hello world'-esque

I did notice that 'Share this message' popped up (& was clicked) before the scrambled message appeared.

I'm seeing reports of 404's popping up when using the back button - might be a separate issue
