Garmin Instinct sleep not tracking since 08/11/2025

Hello,

My Instinct on 08/11/2025 was the last time it tracked my sleeping. Activities like walking, heartbeat and steps are working. I check all the settings on the watch and the software. I'm using IPhone XR and Garmin instinct original. I have rebooted the phone and the watch no luck. Any help will be appreciated.

  • Instinct 1st gen, or another version? If instinct 2 or 3, then does it show any sleep directly on the watch, on the Sleep glance? And does Garmin Connect show any heart rate during the night? Are your Bed and WakeUp times set correctly (for example not inversed, an no mixup of AM/PM)?
