Toca Boca Lost All My Purchased Content on iPad

I have been playing Toca Boca on my iPad for a long time and have purchased a large amount of content through in-app purchases. I spent over $20 in total on various packs, including houses, buildings, schools, and workplaces. However, when I opened the game again about two months ago, I discovered that all the content I had purchased had disappeared, and I can no longer access any of it.

The app also does not have an option to sign in with an email address or account, so I am unable to restore my purchases. I have not received any warning, notification, or refund. It simply appears that all the content I purchased has been deleted.

I request that Toca Boca and the relevant parties restore all my missing purchases to my game or, if that is not possible, refund the money I spent. I expect a response as soon as possible and a resolution to this issue.
