RG-W06: A watch entry was dropped while your iPhone store was rebuilding
An entry from your watch arrived while Regularity’s database on the iPhone was briefly being rebuilt (for example, after changing the iCloud Sync setting), so it wasn’t imported.
What to do
This looks like a problem in the app, not something you can fix in Settings. Please email support@cadentiahealth.com, mention code RG-W06, and paste the text from Copy status report in Regularity’s Status screen. The report contains app and system versions and status identifiers only. It never contains your entries or reminder times.
