There's no question that Georgia never had significant if any latin rite connections in liturgy.
I think this view is true though for Slovakia/Moravia and Croatia, in those regions it seems Cyril and Methodius introduced a Latin rite translated into Slavonic. Within two centuries after the eastern Franks/Germans/Ottonian empire controlled them politically they tried to switch it back to latin again, which was the cause of much consternation and strife. To some extent it seemed to leave them more open toward the protestant reformation in those regions, having long time frustrations with Rome and it's germanic leaning prelates/nobles. Moravia later became a famous protestant region..
That is a very interesting topic, regarding what SS. Cyril and Methodius introduced, and where. I always ment to read a book about it. Someday !
