Some apps have disabled the screenshot-function due to sensitive or copyrighted material, for example Netflix, bank apps and so on. Is it during any specific kind of use that you are unable to take screenshots and do you receive any kind of error message when you try?
Please return with this information and I will do my best to assist you!
