This sucks. Legacy is INFINITELY better for those like myself working on stories with LOTS of Lore!
Have an option to KEEP using it, and do not make it a force opt-in!
If you do? You are promoting “Workflow Disruption” for users like me!
I had 39 memories stored in the old system, and the new “summary” remembered jack crap. 
This is what i have trouble with too, the sumary is FAR TOO SHORT to store all 36 legacy memories i had prevously.
Keep the Legacy, or i will boycott you, ditch you and cancel my Plus subscription!
