Thanks for getting in touch and apologies for any confusion! Shortcodes only apply to our WordPress plugin, but this is still possible with TubePress Express. Here’s what to do:
At http://dashboard.tubepress.com, select “Edit” for the gallery you want to change, then navigate to the Player tab. You’ll find the “Show related videos” setting towards the bottom (you will likely need to scroll down to see it; screenshot here 1). Toggle that setting to the greyed-out off position, click “Save”, and you should be all set!
Let us know if there is anything else we can do to assist, and thank you for using TubePress!
