Comments, reactions, and activity
On a shared idea, everyone can comment on any section and react with an emoji, viewers included. Tap a reaction again to take it back. You can delete your own comments, and the owner can delete any comment on their idea.
To see what's changed, tap the ⋯ menu and choose Activity. Anything new since your last visit is marked, and a dot on the menu tells you there's something to see.
Comments pause while sharing on an idea is paused.
