My Apple Watch Series 4 (updated to the latest software version 6.0.1) seems to start the monitoring the noise level (and send reports in background to Health app on iPhone) only after I start the Noise App during a day. The day after, in order to start the background monitoring activity, I need to start again the Noise app.
I activated the Noise monitoring on Settings/Noise on both Apple Watch and iPhone app.
Is this behavior normal?
Thank you for your help
