You are now able to add multiple emoji reactions to a single message. Previously only one reaction could be added. When adding an emoji to a message there is now a More reactions button where you can select and add additional emojis.
Reactions are displayed in order of popularity, while ensuring that each user’s own reactions are always visible. To maintain clarity and prevent clutter, emojis are limited to 20 reactions per user per message.
When there are too many reactions to show, users can hover over the number (+6 in this image) to see all reactions.
