I frequently fat-finger both selecting the emoji icon and the X to close it, which results in accidentally hitting whatever emoji is closest to the X on random posts/comments. Is there a way to remove this reaction once I’ve done it? I know I can change the reaction to a different one, but if there’s a way to completely remove it I’m missing it.

Exactly! 😂

No but if you do a second reaction it automatically replaces the mistaken one.

Thanks for the response! If possible it would be great to have an option to remove a reaction in the future, but it’s not a huge issue.

Yes, I agree.

Same thing happened to me. I'd appreciate being able to click the reaction I make on the comment to get rid of it entirely.

Also, I'm guessing these reactions only show for PieFed users and do not show up as comments or anything for people on Mbin or Lemmy?

That's right. For other threadiverse software, the reactions just look like an upvote since they don't understand the emoji payload.
