A few days ago (can't tell exactly when, I only noticed it when I got a notification on Intervals.icu) my watch switched data recording from "every 1 sec" to "smart".
It may improve the battery life, but reduces data accuracy. This should be my selection and not change by itself. I am sure I had it set to every 1 sec.
I checked my bike computer and it was also switched.
Can others confirm if they see this on their watch as well? Did Garmin just decide to change it without telling/asking?
