Thanks for your support attached is my access for the admin, so in the Media library you should see the file called: convite-logo-dark.svg thats the logo that it is supposed to appear on the mobile versions
also I would like to ask you one favor, Ive activated the pop up message and it works perfectly on mobile phone but it is not been displayed on my laptop, do you know why?
I have checked you header builder in mobile view. You have configured everything properly, however, this SVG format is not supported. This logo becomes too small http://prntscr.com/jml255 You need change width as shown http://prntscr.com/jmkz87 or upload png.
