Freezes on my iPad air2 – Yum-Yum Letters: Learn & Trace Review

The app just freezes after the logo starts.used to be a great app but now it's worthless unless the problem is sorted out. Your update on December 12th still hasn't solved the issue....:(((( Updated review December 14th/2017 Thanks for contacting me by email and giving me useful tips. I deleted the app and installed it again and the problem seems to have gone, earlier It used to freeze at the kindermatica logo. I love your app and constantly use it for my toddler kid who is just learning alphabets. I hope you make future updates keeping slower older iPad Air devices in mind. ???
