issues related to the homepage in Superset version 5.0.0
<!-- Answer -->
For blank dashboard thumbnails, make sure you have these feature flags enabled
in your superset_config.py:
```python
FEATURE_FLAGS = {
"THUMBNAILS": True,
"THUMBNAILS_SQLA_LISTENERS": True,
"PLAYWRIGHT_REPORTS_AND_THUMBNAILS": True,
}
```
You also need to have Celery workers running and a cache backend (like Redis)
configured and available. If these are missing or not running, thumbnails will
stay blank. If your dashboards only have markdown (no charts), thumbnail
generation can fail due to Playwright timeouts—this is a known issue. You can
try adjusting screenshot-related config flags (like SCREENSHOT_TILED_ENABLED
and thresholds), but they only take effect if PLAYWRIGHT_REPORTS_AND_THUMBNAILS
is enabled. Check your worker logs for errors if thumbnails still don’t appear.

[Celery/cache
requirement](https://github.com/apache/superset/blob/master/superset/models/dashboard.py)
Superset does not support per-user homepage dashboard redirects out of the box.
There is a DASHBOARD_TEMPLATE_ID config that copies a template dashboard to new
users and sets it as their welcome dashboard, but this only applies to new
users and not as a redirect for existing users.
