I see from the light curve the slow steady decline (~2 magnitudes in V over 70 days) has come to an end and the brightness is now dropping rapidly (~1.5 magnitudes in 12 days) This behaviour is similar to that seen in type II-P supernova following the plateau period so SN 2023ixf may have characteristics of both type II-L and II-P, similar to supernova like 2013by discussed in this paper for example
