I have a C425 Outdoor camera.  The only time it senses motion is when I have the app open on my phone and actively looking at it - and eve then it is pretty erratic.  With the app miminized I get no motion dectection and no push notifications.  I have read in some of these forums that it is a firmware issue and I have tried to upgrade my firmware both automatically and maunally and both say I have the latest firmware version.  My version is V 1.2.21 Build 240809 Rel 52696n.  One of the posts referred to a firmware of 1.35 something but I can't get past the 1.2.21 that came with the camera.  Can anybody give me an idea of where to look next to sort this out?  I am using it in an area where I am trying to detect wildlife through a push notification.  Thank you in advance for any help given.  Bill
