2021 Specialized Diverge released

its been a while here in this thread but I hope to find some answers.
I want to buy a Diverge and struggle with the sizes. I am 181cm with inseam 86cm. I am riding a Müsing Crozzroad Disc in 56 and looking to buy a Diverge. Not sure if a 54 or a 56 would be the better fit. I already tested the 54 and the reach seems normal but i was a bit low. normaly I ride a saddle to bar distance of 5-6cm which is fine.
Would be great if you could share some experiences.
Thanks and regards!
