My daughter's iPhone 5 with no SIM card is connected to Koala and her profile blocks social media. The lock screen still shows notifications for Instagram and snapchat. When clicked, the app opens and says "couldn't load media" (Instagram) and "Could not refresh. Please try again" (snapchat).
My objective is to allow the phone to be with my daughter when she is doing homework and to stop her being distracted by these notifications - to become immersed in her homework.
This works against that objective.
