"[15] Robert Marshall of Hypebeast hailed the track as " perfect marriage of the trio’s distinct sounds, while also proving Blake’s sonic progression.

"[17] A music video for "Mile High" was released on 3 February 2019, just hours before Scott's performance at the Super Bowl LIII halftime show,[18] and had previously been teased on Blake's social media.
