Version 3.3.1 is currently rolling out. You can usually install it immediately by opening Diarium’s store page manually and checking for updates.
I understand the concern, but I currently don’t plan to copy feed data permanently into journal entries. Health data is sensitive and can change over time. For example, today’s step count is incomplete until the day ends. Storing it automatically could therefore create outdated values or require Diarium to modify existing entries repeatedly.
The feed is intended to display the current data from its original source, not to serve as a backup or migration system for health data.
