LimeSurvey version: LimeSurvey Community Edition Versão 6.6.6+241002
Own server or LimeSurvey Cloud: Own server
Survey theme/template: fruity_twentythree
==================
I'm editing the fruity_twentythree theme and I noticed that my logo is not appearing in the mobile version in a vertical position, only horizontally.
Where should I change the code so that the logo appears even when using the smartphone? I really appreciate your help.

You may remove this  "d-none" in the "nav_bar.twig"
