It's android using Google drive as cloud folder .
I  choose "sync library" from the main menu. Then "synchronize to a cloud folder " from the popup menu 

In the next screen I always have to press the folder, select Google drive, and then the correct folder.. in the last step it does remember the folder I last used, but I have to go through pressing folder and select Google drive .
If I don't the start button is greyed out
