Switching back & forth from business to personal lowering engagement

I recently created an IG account for a friend for their Etsy store and after their first post got around 50 likes in one day, I figured we might as well make it a business account. The second post the next day got a fraction of the engagement. I thought maybe we should switch back to personal to fix it so I did that but the engagement got hammered even more. This is clearly IG thwarting engagement and reach on this account because of all the switches. My question is, will they take that account out of the penalty box and will it see normal organic engagement rates like I saw the first day?
