No heart rate zone showing last two days?

[tonedog]

I’ve just spotted that my heart rate zone data has a gap for the last two days. I’ve worn the device almost continuously. No other known issues with it. Any ideas how I can get help? Thanks!

Did you actually work out yesterday? I had a light work out yesterday and today I haven’t done one yet so won’t have hit HR zones 1-3 yet.
