My Dot is unable to launch sub-chats and delegate tasks. Its useless

A user reports that their "Dot" AI assistant, which initially worked well for three days, became "useless" after an update. They describe the Dot as having been highly productive, capable of understanding multiple streams and managing tasks, but now it functions merely as a "glorified assistant" that cannot launch sub-chats or delegate tasks, instead relying on the user to manually spawn agents. The user is asking if others are experiencing the same issue.
