I try usign the dropbox integration that was added in HA 2026.04.
I have the custom credentials set up and it seems to connect (Dropbox website, link app,...)
In HA it lists as a service under the integration.
Selecting it as a backup location works as well, but the backup itself fails to upload.
I am getting following log errors:
Logger: homeassistant.components.backup
Source: components/backup/manager.py:656
Integration: Backup (documentation, issues)

Any help would be highly appreciated,
thanks
