Am I doing something terribly wrong or is PouchDB 8 not saving data quickly or reliably?

### Issue
I've implemented a PouchDB database in the browser (it's an Android webview). I get very strange / unreliable results.
For example, when I save data for example strings to the database, the .get function sometimes returns all, sometimes it literally misses puts (retrieves less than what was inserted).
I thought maybe I made a mistake with my code, but strangely enough, if I close my app, reopen it which opens back the database, it has even less strings saved.
This was intended to be used entirely within browser and no sync.
Would that be why my results are inaccurate?

### Info
- Environment: Android WebView
- Platform: Android
- Adapter: None set, should I have explicitly set this?
- Server: None, is this a problem?
