This can happen if you use more than one AutoFill enabled database on iOS (or use Safari AutoFill on macOS). Due to a deficiency in the API provided by Apple we can only do one of the following when telling the AutoFill system about entries/suggestions:
- Add an entry suggestion
- Clear all entries
If you only have one database with AutoFill enabled, we can safely clear all entries, and re-add the afresh every time you Unlock your database. However, if you have more than one database, Strongbox cannot clear entries, because it would not be able to re-add the entries from the other databases (they've not been unlocked!).
This is a less than ideal situation. The best thing to do is to either:
- Use only one AutoFill enabled database
- Regularly purge the AutoFill suggestions by toggling AutoFill off for all databases, then back on.
You can toggle AutoFill on or off for a database by simply going to:
Unlock Database > More > Database Settings > AutoFill Preferences
