Not sure why my latest activity 31 May 2020 is not added to my intensity minutes

Maybe there were simply no intensity minutes in it. Could you share the activity as weblink, and post the link here? Looking at the HR graph and your HR zones, it is then possible to judge whether you deserve any intensity minutes for the activity or not, much better.

1. Thanks so much Trux. Weblink is #beatyesterday

Yes, it is what I suspected. If you look at your HR graph, and at the HR zones tab, then you see you've spent most of the time in the comfortable blue and green zones. There were only some short burtst of higher HR, but for the effort being counted as intensive, you must reach or exceed 10 consecutive minutes where either your step count rate or heart rate is elevated above the threshold that is considered moderate intensity.

Read more about it in the document How Does the Intensity Minutes Feature Work on My Garmin Watch?

In other words, it means the next time you have to work harder

Thanks so much for clarifying. Really appreciate it mate!
