I just updated to 3.0, and I will have to go back
the reason is now the preview window is useless when you don´t have the license installed. A full blue screen hide everything!
we work with 2 computers, and we alternate the enscape seat when the definitive render/video is needed
But until now we used in the other computer the preview with trial logos, just to manage the scale, assets, colors,...
we don´t understand the change. But affect too much our work flow
so if you work also this way, I recomend you not to install the upgrade
