Instinct Solar 2 has stopped tracking sleep and other data

Over the last couple of days my watch has stopped tracking sleep data. It started with me having difficulty syncing and has now completeley stopped tracking that data.

Is it really a problem of tracking the sleep (no sleep data available on the watch), or rather of the syncing (no data available on the app)?

In the first case, the most frequent reason is the battery saver disabling the HR sensor in the night, but there are also other options. You'd need to tell us more details.

In the second case, I recommend to Remove and Add a Device From the Garmin Connect App | Garmin Customer Support, then log a few minutes of steps and HR, and record a test activity, wait till the next morning, sync, and see whether it helped. If not, then have a look at the Troubleshooting guide for (some) data missing after syncing for more tips.
