Received my evisa in an email Feb 3! So it took 9 days total. My timeline:
Jan. 26 started application
Jan. 28 got email stating "Photograph is not in compliance. Provide a new one, not selfie, white background, dimension 413x531 pixels" (it was a photo I took myself and sent to online service to make compliant")
Jan. 29 got a better photo taken at Staples "Passport Studio" and made sure they knew it was for Brazil EVisa because they have the proper specs for all countries.
Jan. 31 I checked online and saw the photo was accepted and my status was "Approved"
Feb. 3 - Received email with E-Visa attached.
