Version 1.3.9
This release focuses on live-event reliability and commissioner tools, validated through our public TestFlight beta at real events.
• Rock-solid scoring: scores now save to a durable queue and confirm only once the server has them — they survive spotty signal, app restarts, and a dead phone, and never block the rest of your group.
• Commissioners can manage the field from their phone: mark a no-show and reinstate a player in two taps, no laptop required.
• Cleaner payouts: a clear "settled" state once an event is closed out, and event lists now sort most-recent first.
• More accurate games: removed players no longer affect skins, points, or the leaderboard.
• Scorecard, Hole History, and season standings fixes for clearer, more accurate stats.
Thanks to our beta testers — your live rounds shaped this build.
