I have created a new child theme from Luma. The admin panel recognizes that it's registered and I have set it up to be used for my store.
One of the things I tried to achieve was changing the logo for a store, tried to define it in default.xml, and flushed the cache, but nothing changed on the frontend.
Afterward, I tried to insert a container with a block on top of the header, but also no sign of any changes.
What exactly I am doing wrong? Can't seem to figure it out with just the help of Google.
