The use of the Horizontal gallery in PowerApps comes with the limitation that scrollbars cannot be customized. As an alternative, I attempted to use the Show Navigation feature of PowerApps.
However, due to the differing widths of various galleries, the positioning of navigation buttons is inconsistent. Regrettably, PowerApps does not offer a direct property to anchor these navigation buttons.
In some instances, the buttons appear midway through the gallery, while in others, they are positioned at the edge of the single page view.
