What's New
Data Persistence Fix
We identified and fixed an issue where vials and other data could disappear after being added. This was caused by iCloud sync
overwriting local data with an empty or outdated cloud state — sometimes within seconds of saving.
What changed:
- iCloud sync is now automatically paused when a data conflict is detected, preventing the cycle of data loss
- Your local data is protected and will no longer be overwritten by an empty iCloud state
- Backups and recovery are more reliable
- You can check sync status and re-enable iCloud sync anytime in Profile > Settings
If you've been affected by disappearing data, your vials should now stay put. We're sorry for the frustration — this one was
tricky to pin down but it's locked in now.
