iOS Need purchase it again after replacing the equipment.

[Yoiawa]

I bought this game on my iPad before, but when I tried to download it on my iPhone, it showed that I needed to purchase it instead of being able to download it directly. I got in touch with Apple's customer service. They said it might be a compatibility issue and suggested that I give feedback to the developer.So I’m writing here.(I’m Chinese and use translator to write this comment.If there’s any issues in my language,I’m sorry for that.)

What iPad and what iPhone are you using?

Are you using the same Apple account?

was it the paid or the arcade version?

Make sure you're using the same account, or if on another account, make sure that you're in an apple 'family' together, and you can use the family sharing feature to download the game using the purchase record of the first account.
