Two weeks ago I updated the firmware of my Instinct 2s and, since then, I have lost all monitoring data in the iOS app: heart rate, HRV status, steps... 
Only the activities performed are now being synchronized.

I recommend to Remove and Add the Device From the Garmin Connect App | Garmin Customer Support, then log a few minutes of steps and HR, 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.
