Answer ID 34904: My Cloud Home: WD Discovery Desktop App End of Support
It is still quite amazing how Western Digital Corporation and My Cloud Home owners ever thought that they could have owners pay ~$100 for a 4TB cloud storage hardware and have full WD relay server cloud service access for life for 30 users or more from the desktop, and how this could ever be a sustainable and profitable business model. And this started back in 2018 to 2019.
The same service for 30 users now on Google Workspace is $12 minimum per user or ~$4,300 a year for 30 users.
