Good day. Purchased a garmin Marq Expedition 2 months ago. Everything is okay. Updated about a week ago to latest firmware 12.2 and had no issue so far.
However, last night, the marq didn’t record sleep (widget says no sleep data recorded). I did not changed any of the settings from previous days (it recorded fine until last night).
heart rate was recorded for the night so did pulse ox and look exactly like other nights.
I also went to bed and woke up at similar times.
i have since restart to Marq and fully charged it.
I had noticed that my battery witch was showing 6 days yesterday evening was only showing 1 day this morning.
i will look again tonight and revert with results.
luckily this will be a one off.
