What's Wrong?

Seems a different conversation (totally out of context of my follow-up question) was injected in the conversation (maybe some concurrency issue on your side?)

Version: 2.1.47
Sonnet 4.6

I have taken screenshots, but I am not sure whether I should share them here.

What Should Happen?

Messages from other conversations should not be injected to your conversation.
