Moen Flo - HASS vs Flo Website

My last few weekly reports from Moen about my water usage have had some odd gaps in them. Days when I know I was home but they show no water used. Oddly, the Home Assistant report shows what I’d expect in terms of water usage. What makes it odd is that the Flo integration uses cloud polling to pull data. How can the source be wrong but HASS be right?
