Hello Dagmara,
Thanks for posting this, I had the same question. During the Webinar they mentioned end of day Tuesday or end of Wednesday at the latest, but as we see that isn't the case.
It was a lot of information to take notes on so would be good to review the video.

Any idea when yesterday's webinar recording will be available to watch ?
They claim this is the Webinar video and broken the video into segments. Not sure if it is the same recording, but giving it a look today
