I have a Huawei Honor 5X.
Today while rummaging around I discovered the app lock - immediately clicked to activate it, passowert forgive and then opened Whatsapp enthusiastically.
But there was nothing. I came in quite normally in every app.
Did I forget something?
I was no longer shown after password assignment.
Maybe you have to click somewhere, which app you want to lock
And where? Neither there in the settings nor in the apps themselves, I can choose something
