Received my e-check by email on 5/22 while status on site says it was mailed 5/14 for offer date 4/1/2018.
When you print it out, the front and back appear on the same page. Citi mobile app could not automatically take a picture of the check as printed. I had to cut out the check images before it was able to photograph them. Guess it didn’t help that I forgot to reset the print size to 100% (had it at 80%) in Google Chrome.
