3&5 year olds love it but sound stopped working – Curious About Shapes and Colors Review

We discovered this app at our library and I bought it despite some bad reviews of it being too simple for a long car trip. Both of my boys love it but it suddenly stopped having sound! Both the app on our iPad and the app on my phone dont have any sound! Super frustrating since it’s great reinforcer for the 3yo still learning shapes.i can’t figure out how to fix it because i don’t seething in the ‘parents only’ info and the app is t showing up under my phone settings. hopefully an update with a fix comes soon for the 9 hour car ride home!
