Both yesterday and today some of the live stream sessions weren't available. I have digital access and so I hit the find live stream sessions. It lists the sessions for the current time but when I try to get in the page says that the session is live in 1 Day(s). I was never able to get into the MS 365 session while it was being streamed but yesterday, I was able to get into two sessions but only after I kept checking back. It took about 20-30 minutes when it finally allowed me to join.
