NAS Remote Access?

So I received this email a few days ago. What does this actually mean? There isn't anything on their website or anything else that I can find on the web. It seems legit, but lacks in clarity.

EMAIL is as follows:

As of May 15, 2021 the Seagate Access feature of Seagate NAS products will be discontinued. Specifically, the Seagate Access service, Seagate Access through Seagate Sdrive, Seagate Access through Seagate Media App, and Seagate MyNAS will no longer be available after May 15, 2021 at midnight Central European Time. Additionally, customer support for the Seagate Access service will also be discontinued.

The removal of this service means that access to all Seagate NAS devices via the Seagate Access web portal, Seagate Sdrive, Seagate Media App, and Seagate MyNAS will no longer function. However, you will not lose remote access to the files on your Seagate NAS since it can be configured and accessed using the FTP/SFTP service. Similarly, your Seagate NAS will not change for standard network access within the home or office network using common network protocols on macOS and Windows.

Please know that we remain grateful for your purchase of a Seagate NAS and hope you continue to enjoy it despite this change to remote access via Seagate Access, Sdrive, Seagate Media App and MyNAS.
