I have an XT Di2 groupset and the chain slap and clanking of rd is just unbearable!
Chain length is per shimano guide and checked by a mechanic.
B tension is above average as well.
As you can see from the video the chain slaps the ground and the RD bends forward.

The rear derailleur little tension level is definitely in the up position?
Is your clutch on?
How stiff does the spring feel when you pull the cage forward? The di2 units I’ve had in the shop are super stiff
