I seem to be having the same problem with my spotlight cam, I noticed this seems to happen a lot when the motion is detected and I get the notification, I go to look at live view and it seems to be stuck on activating device and trying to process the recording rather than go to live view. This is intermittent roughy 50% of the time.
I also find the motion zones settings for this cam really poor and not very adaptable. There should be a lot more scope for adjustment and variation. The app adjustment for this is also poor as you can’t see as you are adjusting the size?
