Mystery with Stream-Users cant see upload video and create channel is missing for sometime.

Is this still an issue for your users or did the issue correct it self since last week?

If so can you send us the info from ? > About Microsoft Stream, the Session ID and where your data is located?

I just looked through our open and resolved issues for Stream and didn't see anything that looked like it was related. I'll check with some of our on call engineers and see if they know if we had or have a related issue going on.
