v1.7.1

This update mainly improves the Apple Watch experience and fixes a display issue on the Insights screen. 【Improvements】 · Swiping up and down between the Apple Watch Home and Today screens is now more responsive, without getting stuck halfway through a transition. · The title at the top of the Apple Watch Home screen now uses shorter wording, so it is no longer cut off in German, Spanish, and other languages. · The HRV card title on the Apple Watch Today screen is now clearer. The app name and version number have moved to the bottom of the screen, giving Home a cleaner look. 【Fixes】 · Fixed an issue where the date bar at the top of the Insights screen could have an incorrect collapsed state or a transparent background after switching tabs and returning.
