That was the feeling I had when preparing and delivering my lightning talk for the Tridion Expert Summit 2021 for the Americas earlier this year.
Mainly, in preparation for the TXS event, we practiced in our streaming backend system, which is distinct from the digital asset management used to deliver pre-recorded videos, which is also distinct from the event front-end.
It took a moment for some of us presenters to clarify the difference between the off-stage and on-stage (or backend and frontend) elements of the setup.
