Created Unassigned: App does not sync with Cloud database (beyond initial setup) [561]

__How do I force the "Keepass2Android" app to sync with the Dropbox database?__
_________________________________________________________________________________________

I have installed and completed the setup for the "Keepass2Android" app.

I have my __desktop Keepass application__ set to sync to a copy database within __Dropbox__; Keepass2android is set to use that database.

When the android app is loaded, in the top right corner there are 3 vertical dots.
Press that, and below there is a button labeled "___Synchronize database...___"

Pressing that, a message pops up stating:

"___Working___
\______________
___Synchronizing Cashed Database...___"

How do I force the android app to sync with the Dropbox database?

Thank you for your time and any help you can give.
