Have just upgrade to the Defy Advanced 1! My first time with a Di2 groupset, what’s everyone opinion on the synchronous shifting?

I use it and it’s honestly great when you get it how you want it, I leave mine to change the front based on rear gears, I tend to go back 2 cogs when going to easier gears so the drop from 52 to 36 at the front isn’t as big. I think when I’m going on power it’s only 1 difference but could be wrong. I have it setup so my head unit beeps at me when it’s going to auto shift next change just in case
