If you experience difficulty watching Philo Edu on your iPhone or iPad, oftentimes deleting and redownloading the Philo Edu app resolves the issue. But if that doesn't do the trick, please submit a support request explaining the issue and include the following:
Device model (e.g., iPhone 5)
iOS version (Settings > General > About > Version)
IP address (Settings > WiFi > Network you’re connected to > IP Address)
Philo Edu app version (Philo Edu > gear icon > Version)
Is your device jailbroken?
