Letter of Rec

So for early action, I submitted my application a week before the Nov 1 deadline to University of Michigan. However, I changed my recommender the day after I submitted my app. On Common App, it shows that my teacher submitted his letter of rec the day after I had invited him but when I checked the portal the college provided me, it shows as the letter was not received. Do I contact the university or do I just wait till it’s processed? please help
