Why can't I grant apps permission to write to my SD Card?

[AC Question]

I'm trying to put a file folder on my external SD card, but to do that I have to grant the app I'm using permission. I follow the instructions perfectly but it still doesn't work.
This is really getting on my nerves, if anyone has a way to fix this, I'd love to hear it.

Which phone?
Which version of android?
Which carrier?
Which app are you trying to use that needs permission?
