<!-- Answer -->
In Superset 6.0.0, the way to permanently change the app icon has changed:
the old `APP_ICON` and `APP_NAME` config options are deprecated and ignored if
any theme config is present. Branding is now managed through the theming system
using `THEME_DEFAULT` and `THEME_DARK` in your `superset_config.py`. To set a
custom logo, add something like:
```python
THEME_DEFAULT = {
"token": {
"brandLogoUrl": "/static/assets/images/your_logo.png", # your logo
path
"brandLogoAlt": "Your App Name", # alt text
# ...other theme tokens...
}
}
THEME_DARK = {
"token": {
"brandLogoUrl": "/static/assets/images/your_dark_logo.png",
# ...other tokens...
}
}
```
[Reference](https://github.com/apache/superset/issues/34824)
For the loading icon (spinner), there is no theme token for it. It's a
static asset bundled by the frontend build. To change it permanently, replace
the source image (e.g., `loading.gif`) in
`superset-frontend/src/assets/images/` with your custom version, then rebuild
the frontend with the appropriate npm build command. Do not replace files
directly in `superset/static/assets/images`—these get overwritten on every
build or deployment due to the asset pipeline and content hashing.

Important: Superset 6.0.0+ requires Node 20.x for frontend builds. Using
Node 16 or 18 can cause build failures or missing assets, which may prevent
your customizations from appearing.
[Reference](https://github.com/apache/superset/issues/34577)
After updating assets and rebuilding, clear your browser cache and
localStorage to see the changes, especially if you've used the Theme Editor
before.
If you are running in a multi-tenant or advanced deployment, make sure the
database is migrated and theme seeding is complete, as themes are now also
synced to the database.
