Transunion not updating

I fully paid off 3 credit cards. One of my cards was reported to equifax and experian on February 26th but transunion still has not updated. It’s been 40 days. Should I wait longer before panicking? I’m trying to buy a car and transunion is still showing 640 while equifax is showing 738 and experian is showing 722. I filed a transunion dispute for accuracy. Anybody had any success with a situation like this?
