New to kobo, imported books progress won't sync across devices

I'm totally new to Kobo. I just got the libra and expected to be able to sync my reading progress between my libra and the Kobo android app. I just learned that kobo only syncs Kobo purchased books.

Is there a work around? I don't mind installing a new image..this is a must have feature for me and I can't find another ereader with side buttons at that price point.
