Rio stopped working. Will the Christmas app do the same down the road?

I ask this because in the Christmas app, I get 198 daily tickets. This allocation represents my completing the collection card. When I open the legacy bingo app, I see 195 daily tickets.

Why is there a need for the second app when it only causes more discrepancies? It makes more sense to me if you can't add a room to an existing app, just issue an app update to be inclusive of ALL rooms rather than fragment it like it was done with Rio and now Christmas.
