Cannot Sync Ubuntu to Android

I have been using Enpass on a daily basis for months on my desktop and would like to sync it with my Android phone.

Desktop OS - Ubuntu 16.04 64bit

Android OS - 7 up to date

Here are the steps I have taken, each ending in failure.

1) Sync to Cloud with Google Drive:

On Desktop: Tools-->Settings-->Sync
Choose Google Drive
Authenticate.

On Android:Open app. Restore my existing data.
Choose Google Drive.
Choose my google account
Message: You are using trial version - only indicates I can have 20 entries.
Message "Please provide password of Enpass data on Google Drive." I have entered both my master password and google password but both get a "Passwords did not match" message.

2) Sync with WIFI

I downloaded the backup file on google drive to local computer.
Restore my existing data
Choose WiFi
Message about trial version
Go to URl listed
Browse for file
Click on Submit.
Android asks for Master Password.
I enter it(I am positive I am typing it in correctly, this password is stamped into my consciousness). I get a message "Incorrect password or invalid file."

I do not know what I could be doing wrong. Is it available to sync between the two OSes?Are the files not compatible?
