What's new (v1.1.0)
What's New:
Hosts can now configure pool rules — set details like tiebreaker method, payment instructions, and entry deadline, then choose which sections participants can see.
Participants and guests can view pool rules anytime via the "Pool Rules" button on the entries screen.
Guest participants can now switch between pools directly from the entries screen — tap "Switch Pool," enter the new invite code, and you're in.
Bug Fixes:
Fixed an issue where the entries screen could take 20–30 seconds to reflect the correct pool after switching as a guest.
Fixed an issue where a competitor's name occasionally displayed as "Unknown" on the entries screen.
