Bests & Worsts Reviews from Amazon

I really like that this app is available for the kindle fire HD but it doesn't work half the time. It takes a while to load videos and after one minute or so the screen turns black but the sound is still going. If i tap the home button it shows me the carousel with the PBS audio still running in the background. I need to force quit the app 90% of the time. I actually deleted the app off the Kindle fire HD but my daughter wanted it so much i needed to download it again. However she gets so mad when it doesn't work smoothly & that is getting on my nerves too. I'm hoping the problems will be fixed soon.
