As of May 5th *none* of my activities have shown on Intensity minutes- despite recording activities from Zwift(HRM Pro), Edge 1030, Fenix 6X Pro which normally all contribute perfectly.
My heart rate zones still appear to be set correctly. My most recent activity shows 86% of a cycle race in zone 4 and 5, yet Connect still doesn't show any intensity minutes.
It has always worked well before, accepting data from various sources without trouble.
