I took the exam recently, on March 6th, and got my results back later on March 18th. I have some friends that took it the week of March 8th that are still waiting for their scores. It seems like the last few batches have been released on Wednesdays, around 10-17 days after taking it, despite the "3-4 weeks" they say officially. I was concerned last week too, but according to the ADA's COVID updates (as of March 20th), scoring of exams taken already is still going on without any delay despite the test centers closing down. So hopefully you don't have much longer to wait - best of luck!
