No "App Lock" Function on Amazon Fire HD 8 (10. Generation)

[Mr_Frank 0]

I am using ESET Mobile Security (64 bit) v.8.2.9.0-0 with the ESET HOME license ESET Mobile Security Google Play on my Smartphone.
There I can find the "App Lock" function as well.
Now I would like to use the same licence on my Amazon fire HD 8 tablet. The installation works fine, but at the tablet I'm missing the "App Lock"-Function. My question is why? All other premium functions are still there. Any Idea?
