Major bug at the moment. When you open up the app and click on a camera to live view there'sno problem, then you click on the option to muti view all devices it work fine still but then when you try to click to view any device , the view goes black and when trying to reload/play it sticks on 99% . Really big issue this . Will up the review to 5 stars when fixed . Thank you Edit: ive rebooted and all devices an app are upto date too.
