The version that I have installed is 1.7-13.
While trying to install 1.8.17, I got the message App not installed as package conflicts with an existing package. The workaround that worked was uninstalling 1.7-13 then installing 1.8.17, and then syncing with the desktop.

Posting the updated APK Everdo for Android 1.9.9.
Release Notes
Amazing! Does the background sync work with both the local network sync and the encrypted sync?
Yes, it should work for both
It works! This feature is very convenient, thank you for implementing this.
