We had announced that there would be price changes coming for XBOX and Android a little while ago and then sharing updates as I got word that those changes ended up being delayed
I can chase up with the team if those are the intended new prices, or if there was an issue with updating them.
But checking the USD value of that new (530 UAH is around $11.90 USD) it does not seem to be well beyond what was expected. At the moment, I do not think this new price is a bug, but I will confirm.
Some regions saw less than a 5% increase, and then some regions saw above a 15% increase.
