Sleep is recorded everyday. I can check on my watch. But in the app, historical data shows only alternative days. Not continuous data. But in the watch, everyday I checked the data is collected. Why is that I don't have idea. Can you help devs?

The weather feature is very bad on my haylou watch 4s. It can only display "light rain" conditions even though the weather is very clear, which is displayed perfectly on the phone's default weather app and other third-party weather apps.

Good hardware (Haylou Solar Ultra), but software is flawed. There’s a huge pace discrepancy when syncing to Strava (Real pace 8:11, Strava shows 7:03). The "Moving Time" data formatting is incorrect. Please fix the export file to meet Strava's standards. UI Request: Update firmware to show Pace, HR, and Distance on ONE single screen during runs. Swiping while running is inconvenient. Don't claim "Reliable GPS" if the data integrity is this poor. Please fix!
