Igarashi (formerly Higashino) - what happened to her?

Anyone knows what happened to Igarashi’s new partnership? They have unfollowed each other on Instagram and Igarashi even deleted their Photo from the Indian Open (they were the winner). Any Japanese here or anyone knows what happened and what will be their plan in the future?

I was hoping that Their partnership would stir up the Women’s double descipline like it did during the Indian Open.
