wrote wrong date on ap exam

Hi I wrote the wrong date on my AP psychology scan-tron on the bubble part, next to my signature and on my multiple choice booklet, I called AP services and they said they don’t think it would make a difference but we can’t tell until the scores actually come out but I have seen people on twitter say that they didn’t get their score because they wrote the wrong date. I wrote 6/20 instead of 5/20. Does anyone know for sure if it will make a difference?
