Yesterday I was riding without navigation turned on, just a regular activity recording.
Maps are the standard ones, nothing third-party loaded.
The ride was long — moving time was 8:17:31, total time 15 hours 30 minutes — which is why the radar battery started running down.
Connected sensors were: cadence, HRM, and a Varia RTL515 (battery was low, then critical low). I had turned off the Varia's tail light to save battery, leaving only the radar function active.
The device rebooted twice, about 20-30 minutes apart, with no error messages at all — it just restarted. After the reboot, the tail light turned back on, and my activity was in a state as if I had pressed Finish but hadn't confirmed it yet — the screen had a red outline and a checkered flag icon.
This issue never happened on previous firmware versions.
If there's anything I can do to help investigate this, I'd be happy to.
