On my site, angelopianoduo.new.sfmf.org/new/ , the mobile logo position doesn't show up when looking at the site on my cell phone.

I have a text logo.
I have the name published in the module
the Logo Module is published
It is on All Menu Assignments

Please advise.

PLease read the docs about this theme:

Warp 7 Templates provides the logo-small position, where you can display an alternative logo image for smaller viewport sizes.

>> Chapter > Logo setup

I have read the documents on the Mobile Logo, and I believe I did everything correctly. Still, it does not show up. I attached a screenshot so that you can see.

I duplicated the logo module. It is published in the logo-small position.

Please advise

It looks like the mobile menu doesn't show up either. It is configured as instructed in the documentation.

Live url please, coz this url is no more working:
