This will usually solve most of the minor issues and also helps free up storage space on your device, but please take note that it will also clear any login details or custom data that you had saved in the app.
The instructions below will guide you on how to do so on your Android 6.x (Marshmallow) devices. If you are still on an older version of Android i.e. Lollipop (5.x) , KitKat (4.4), kindly refer to the article here:
How to clear App Cache & Data for Android (version 4.x up to 5.x)
Android 6.x (Marshmallow)
1) Open your Settings menu and tap on App.
2) Full list of the downloaded apps should appear on your screen.
3) Tap on the app that you wish to reset. In this example, I've selected ITV Player.
4) Now tap on Storage
5) Now click on Clear Data and then Clear Cache . If prompted, click OK to confirm the action.
