Changed view of boards- need to revert back!

I saw a tag on top that said “new view- try it” and now my boards look different with subitems as number and the collapse feature different, how to revert back?

I have the same problem. I didn’t even choose to use the new view, it was just shoved down my throat. Thanks for that Monday. The chat support person said I can’t change it. Time to get off Monday.
