Thank you for te re-upload
make the app a loop neverending loop so that people can practice and benefit from it anyway even if the challenges has ended. You can always add more on the way adding new or similar. Also try to stop collecting data as well. Make it a real app no personal data collected. I invite you to also talk with your customers in case of inquiries. unresponsive customer service is frustrating. Even if it's free you are dealing with awareness. Push yourself more! For the better. ps the history doesn't upload new lessons, the notifications doesn't notify new lessons even if my smartphone is allowing them
