it's most similar to upvoting, but with more emoji. So imagine if HN had an upvote on IOS, but instead on android it left a full message saying

Oh, do iPhone users also see those messages when an android user is in the chat?

I had assumed that reactions worked fine for them and they were unaware that their iPhone was making them look like a bit of a buffoon to the rest of us.
