MyMeets has been updated to version 2.3.1 to include Sweets Meets genes along with the November and December app guests!
Additionally, thanks to @Bolter#7401 we learned of new characters that have appeared in app files with full sets of genes. These characters cannot be made available just yet, but will these be future app guests?
The first two that have full sets of data are Charatchi and Polibaketchi as featured below.
Three other characters which only have partial gene information available are Coffretchi, Yumemitchi, and Kiraritchi.
