Apple has made a new decision requiring developers to display the odds of getting “loot box” items or any item that is acquired by random chance. i assume this will be implemented on the android version as well for at least dokkan battle.
this is similar to jp dokkan as they have had the same rule implemented for awhile.
special thanks to DaTruthdt and tksproule for the screenshots and dokkan subreddit for the article clip.
link to an article describing the situation: https://arstechnica.com/gaming/2017/12/apple-now-requires-app-store-games-with-loot-boxes-to-list-odds/
this applies to all mobile games, not just dokkan.
i believe they are required to by the first of the year so we will recieve the update soon.
