Anyone else sell books fbm

Any one else here that sells books fbm and just having an absolute sh*t day?!? Had issues with buy box eligibility about a week ago and that has apparently been resolved and was I guess a technical issue. Before that I had 3 old policy violations that dropped from my account and the day they fell off my account health rating went down 4 points. As if that makes any sense. U would think it would go up, going from 3 violations to 0. Then this week I had to cancel an order which sucked because it made my cancellation rate go above the allowed percentage, it was at like 3.5%. Mainly because I didn’t really have many orders this week because of the buybox issues. Then I was getting sales normal for a couple days and it was bringing that percentage down hut literally today my cancellation rate is at 0% for the last 7 days. That’s not possible because I cancelled an order just like 3 days ago! I have had only 1 sale this morning and then 1 about 5 hours ago. This is usually what I experience when I am dealing with buybox eligibility issues but right now my buybox eligibility says yes. I find all of this to be too many random issues. Is anyone else experiencing anything similar??
