Get back to the custom logo set in seahub_settings.py

Hi, i’ve set a custom logo in the web insterface but now I want to set it rather by using the seahub_settings.py…
Seems the one set by the web interface takes priority, how can I remove it ?

Why do you not download old logo and upload over web interface?

Three years later and I have the same question. Any answers other than download the old logo and upload it?
