They are still a real problem for me
Every time I post a reply to something with an emoji I get the Oops message
Do I need to update something (some confused smiley emoji thing)
Thank you TC, refreshing to get a useful response :)Delete the emoji and you can then quote the post.
You can add it back yourself after deleting it and it'll still let you post it.
Irritating, but it can be worked around.
