Diablo 4 SSF fix is now in QA as Blizzard focuses on the Tree of Whispers problems
The Tree of Whispers bug could be fixed tomorrow, and the SSF issues are already being tested.

Diablo 4's Solo Self-Found mode could be getting closer to a return, because Blizzard confirmed that a potential fix has now reached QA testing! Do not expect it today, obviously, but if it reaches QA and everything goes well, it should not take too long before it becomes available again.
They also provided another update on the broken Tree of Whispers rewards, confirming that they are trying to have a fix ready tomorrow.
Diablo@Diablo𝕏We’re continuing work to restore Solo Self-Found, with a potential fix now in QA testing. Separately, we’re investigating an issue preventing players from turning in Whispers and blocking further progress. We’ll share updates on both issues as soon as we have more information.…
There is still no guarantee that the fix will go live immediately, as the testing process could uncover additional problems. Blizzard has also not provided a specific release time yet. But at least it is moving in the right direction.
When it comes to the ongoing Tree of Whispers issue preventing players from turning in their Whispers, it seems like they are actively working on it as well. The bug can leave you unable to claim your rewards, and that then blocks you from earning more Grim Favors and continuing your Tree of Whispers progression.
They released a small Blue Post saying that they are still investigating the problem and are currently aiming to have a fix ready tomorrow, but that timing is subject to change.
The team is continuing to investigate this issue. While timing is still subject to change, we’re currently aiming to have a fix ready for tomorrow and will provide further updates as they become available.
Thank you all for your patience.
There is no confirmed workaround either, so if you are affected by the bug, you will have to wait for the fix. We will keep you updated as more information becomes available.
