“All Day” is the group’s fourth official single.

This is the first song from the group to be performed by the 18 members who were at the beginning of the group in 2018.

The music video was released on June 5, 2018. Then on November 5, 2018, an alternate version without former member Lamar Morris was released, where he couldn’t participate in the music video and therefore couldn’t sing in it as well.

This was the third music video to reach 100 million views.

On September 23, 2019, the song was officially released on digital platforms.

In the group’s online show, the Now Love Live Show, the group performed the song with the original fourteen members with the addition of the voices of new members Savannah, Nour, Mélanie, and Alex.
