Question(s) about the interaction between the KI Combo Breaker pack, and the digital version ...

Just so anyone reading this is already aware of that, I'm aware there is a general FAQ for the KI Combo Breaker pack which I already did read, though my questions weren't precisely answered there which is why I'm asking them here. My most important question
is how the Combo Breaker pack interacts with the digital version of Killer Instinct? Apparently I unlocked as many achievements as I possibly can without purchasing additional content despite earning at least two succeeding that, so I was curious if as soon
as I install the combo breaker pack I'll get the achievements I earned unlocked right away? I was also curious if my achievement progress within the digital version - most specifically as far as general challenges go - will get reset beyond the point that
I install the combo breaker pack?

There are a few more peripheral concerns I had, though these are definitely the most important so for the time being this seems like enough to ask here. I hope to receive answers as expediently as possible as I'll likely have a copy of the game in less than
two hours, so I want to make sure I don't screw anything up by rushing the installation of the disc when I could be nullifying progress I worked relatively hard to obtain within the digital version of the game. Obviously anyone who the answer(s) to my question(s)
is definitely welcome to answer those as soon as possible as it would be greatly appreciated. Provided that does happen, thanks in advance!
