Standard navigation briefly appears on mobile.

When I refresh the published website on mobile, the standard navigation reveals for a second then the mobile navigation appears after the standard one is gone. I made a separated component because of it’s complexicity. The standard is set to ‘not rendered’ on smaller screens. What should I do to prevent the standard navigation showing up?

Hello @fiscal_mastodon. Can you DM me your project iD?

Sure I sent it to you! @icaro
