Private Threads are intended for sharing sensitive information.

oh my god, what is this services, i am the one hosting and the one who created this thread, regardless sensitive or not if i request to change the thread to to private what is the issues with this i dont see any issue or problem

I had same issue today, just few mins back. Had the issue for a short period of time. But I am worried about this issue coming again in future.

We are planning for client demos this and next few weeks. And for some reason, this happens in-front of a potential client during a demo session, we will be in a really bad position.

Any reason why this happens? and what can I configure on my-side to prevent this from happening again?

Just had this happen today. From googling it seems this is coming from fastly.
