[Apps] "Clear Cache" button does nothing?

[AC Question]

When I go to my apps in the app manager or storage menu and select an app, it gives me a screen where I can uninstall, clear data, clear cache, or do other stuff. When I hit the clear cache button, it slightly changes color for a second to acknowledge that I hit it, but it does not actually do anything. Nothing changes, no feedback given, double-clicking or holding down my finger on the button does nothing. I've googled it many times and have not found anyone with a similar problem. If you want screenshots, I don't know how to take and send them. This is my first phone and I've only had it for a few months. Thank you in advance.

Welcome.
What device do you have?
Any particular app you are referring to or does it do the same thing on all apps?
