One world ruby status does not mention any free or extra baggage allowance.
It would be wrong to assume that you get the same benefits as a Finnair status passenger because their status is equivalent to a one world status that you have.
As to becoming bronze it's been two days since the flights or two days since the flights have posted? If the latter then refresh their accounts in the app. Finnair won't give any benefits unless they see proof such as the app showing a bronze card
