To update a Logo, you would need to select on Add Logo. From there, when selecting a logo that has the exact same name and extension (Eg. jpg or png), then the system will overwrite the logo that is in the system with the new logo.  You can rename and/or browse for a new image file and click Upload. 

Note: The maximum size that is allowed for upload is 1MB, and optimal dimensions for display on the mobile apps is 140 X 140 pixels.
