Congrats on the promotion. I had something similar happen at the start of this month. My boss annouced she was retiring and I was taking her spot. Unfortunately her bosses boss decided he didn't want to promote anyone to fill the spot. So for the same pay and bonus percentage I have had for the past 6 years, I went from having 9 direct reports to having 11 direct reports and 112 indirect reports, along with the responsibility for the entire state of Michigan for our organization. I look at it as a chance to prove myself at a higher level and use it to advance my career in the future.
