Since the most recent update, my steps are not being logged on the app. Basically seems like the step daily totals is not being updated despite my fenix 5 being synced to the app.
If the steps are counted by the watch, and do not sync to Garmin Connect, despite that other data is syncing all right, then I recommend to Remove and Add a Device From the Garmin Connect App | Garmin Customer Support, then log a few minutes of steps, 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.
