Check who's seen a poll
Open the interaction menu or poll options on the poll card.
Tap Seen By.
A panel opens showing every member who has viewed the poll, with their name and profile photo.
Search the list to check on a specific member.
Note: This is available to group admins for their own groups and to club admins. Club members don't have access to the full Seen By list.
FAQ
When does a member count as having "seen" a poll?
As soon as the poll card becomes visible in their chat thread, the same way regular message read receipts work.
