From Support: WP.comWed, May 27, 1:44 AM To answer your question, you get to keep the Classic Editor.
Just Now: That was never permanent unfortunately. At some point of time it had to go. However, please let me know if you need help with anything related to block editor so I can help you learn more about it.

Your comments appreciated. I’m totally unhappy.
