RG-W07: A watch entry couldn’t be queued on your iPhone
An entry from your watch couldn’t be written to the iPhone’s waiting list, so it was dropped.
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-W07, 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.
