How do I force syncing of data from Health Connect?

In Exist for Android, tap the ⚙ cog icon to open Settings, then tap "Health Connect attributes". Scroll to the bottom of the list, then tap the option "Force 30 day data sync". This will sync all of your Health Connect attributes' data from the last 30 days to your Exist account, and may take a few minutes.

This option is only available once a day.
