The Sforzato DSP-050EX is not yet listed on Roon’s Sforzato Partner page as being Roon Ready.

Therefore, as the message says, it has not yet completed the Certification process.
In other cases similar to this, we have heard back from Roon Labs that the temporary visibility of the device in the app under Roon Ready was due to development testing.
This happens from time to time, and occasionally, it’s possible to even activate a device and get a brief taste of Roon Ready functionality.
Aside from that, nothing has changed in regard to announcements, promises, and timelines for certification.
It is not possible to state when device certification testing will be completed, or indeed whether a situation is reached where both parties (Roon Labs and their Partner) will conclude that testing will end and a device will not become Roon Ready.
