How do I delete a member from one of my group albums?

MOBILE:

iPhone: Go to the specific group album you are trying to remove the member from. Select the Settings icon (looks like a gear/cog). Select "<#> Members" and from the member list select the member you are trying to remove; by sliding left on the unwanted member a red "Remove" button will show up to the right of the member's name. Click "Remove".

Android: Go to the specific group album you are trying to remove the member from. Select the Settings icon (control setting sliders). Select "<#> Members" and from the member list select the member you are trying to remove; by holding down your selection you will be prompted: "Really remove <member>?". Click "Remove".

WEB: Click on the "Members" button at the foot of the cover banner for the specific group album you want to remove a member from. Click on the name of said member and then click the blue "Remove" button.
