M9+ Parental Controls
My M9's parental controls are SLOOOOW to respond, specifically when "pausing" or unpausing internet. Doesn't seem to matter which of my devices I use to pause/unpause and it's very fluid response. One time I pause them and it's instantaneous, the next it can take 20-30 minutes for any changes to take effect. I would assume that in the instance of a TV playing Netflix, the TV is just finishing playing downloaded content, however it also takes forever when I unpause the internet for the TV. It's always been this way; at least since installing the system a little over a year ago.
The device it seems to be the slowest on is an Android phone, however it reacts the same to other Android devices and iPhones, though they just seem to be a little faster.
