NEW FEATURES: • Backdated Service Logging — Log maintenance with the actual date it was done, not just today. Replaced a chain last Tuesday? Changed your brake pads after last weekend's ride? Now you can record the real date so your service history stays accurate. • Date Picker for All Service Records — A clean calendar picker appears whenever you log a part replacement or service interval, letting you scroll back to the correct date before confirming. • Unified Service Dialog — All part replacement and service confirmations now flow through a single, consistent dialog. Cleaner, faster, and no more hunting for the right button. IMPROVEMENTS: • Tap anywhere outside a dialog to dismiss it — standard behavior you'd expect on iOS and Android • Strava sync is more reliable — fixed an issue where an expired Strava token could get stuck in a loop of failed requests, requiring you to reconnect your account • Part replacements are saved more reliably — critical updates now use database transactions, so a dropped connection mid-save won't leave your records in a half-updated state • Faster, more stable server responses — backend infrastructure improvements mean fewer connection errors and timeouts BUG FIXES: • Fixed Strava authentication errors that could surface repeatedly after a session expired • Resolved an issue where webhook processing errors appeared as unhandled server errors • Corrected app behavior when the server returned unexpected responses Thank you for using KOR!
