NotebookLM PRO Change: Is the text box now locked while waiting for responses?
Do I have to wait for the answer to my previous question before asking a new one now?

Hey everyone,
I wanted to check if anyone else noticed a frustrating change in NotebookLM's behavior today, specifically on the PRO version.
My study workflow relies heavily on sending multiple consecutive questions. Since responses take a little while to generate, I usually paste several legal articles one after another so the system processes them in parallel while I work on something else, and then I review them all together.
However, as of today, the PRO version is blocking me. The system now forces me to wait for the current response to finish completely before it unlocks the text box for the next prompt. This has completely ruined my productivity.
The weirdest part? I tested it on my institutional/student account (which is on the Free tier), and it still works perfectly fine over there! I can queue multiple questions without waiting for the previous output to finish.
Has any other PRO user experienced this limitation today? Do you think it's a temporary bug or an intentional update by Google?
