Parental control doesn´t stay on
I have bought F-Secure Mobile Security for 3 devices 2 months ago.
I installed it on my daughters Huawei P8 Lite -android phone. I also installed in on my Samsung Galaxy Tab 3.
In both devices I have set up Parental Control on, but for some reason in my daughters Huawei is doesn´t stay on. Androind version is 6.0.
I have set up it dozen times, every time it seems to be on, but after few minutes it doesn't work and blocked software can open normally.
I have uninstalled software and installed again, but no change. It work exact same way. This is annoing and I don't know what to do.
In Galaxy Tab 3 it work perfect.
What I do wrong or what´s wrong?
