Hi,
I have a background image set with local path. The image source I just copy and paste from the file editor: /api/hassio_ingress/JBXjCQs8FtugrMrpwIgUj0uLhFA6CdElIn7oyMyxKG8/api/file?filename=/homeassistant/background/Dashboard.png
The image is visible, but when I close the browser and kill the session, the background is gone. Only when I open the file explorer again, the image appears again. On another lovelace screen I use a web url for the background image and here it always appears. Any ideas?
