Sim Won’t Call Yoga Instructor (pregnancy task)

Hello! I am playing on mobile. 
I just wasn’t sure if anyone else had this issue, but I’ve complete all the tasks but one on day two of my sims’ pregnancy challenge/gameplay. 

Unfortunately, I appear to be stuck. The sim doesn’t go to call the Yoga Instructor, not interacting with it at all when u hit to launch.
It works for all other phone-related tasks except this one. 

I’m just honestly not sure what else to do or where to go from there! Thank you!
