Something went wrong and Nokia Play To need to close. Try restarting your phone and then reopen the app
I have tested the version 3.0 of the app earlier on a Lumia 520, so I don’t think it is a question of not supporting Lumia 525. ‘Play To’ is one of my favorite and most used app on my Lumias and as DLNA play on my 808 PureView. So I am missing it on my Lumia 525. Hope, Nokia / Microsoft fixes it soon. Are you facing similar issue with Play To or is it working fine on your Lumia runing Windows Phone 8.1?
