Thank you Anders, I had the exact same issue and your solution to use Classic block worked for me.

I want to make sure I understand your recommendation to use the block editor video block. I normally do if video is part of my post, but is this classic block still the best way for the video to show up on my home page?
Love your theme! Keep up the great work!
