May be just me but it looked like they separated way late
I thought so, too.
Looked at it again and it appeared they didn't separate until well after separation was marked on the progress bar and fa after I remember from past flights. Camera angle maybe?
Had me wondering what they were going to do if they couldn't get a separation. That is if they could do anything. Not sure the booster can land with the weight of the capsule still on top. Seems like it should but not sure what effect the extra top weight would have.
