To me it’s a must, that the GoogleFit integration works - more specifically that the blood pressure measurements from GoogleFit are synced. The option is there, but only when setting up the initial integration, then data is collected. When heading to Integrations, then the GoogleFit is set to OFF, but when checking settings for the GoogleFit, then both Activity and Measurements are ticked ON.
Can you share a screencast or video of the data being imported initially when turned on, and then browsing to the Measurements screen and showing blood pressure?
