Sync automatically happens after logging in to the Mobile App, if the sync never completes you need to Clear cache/data. Clearing App Data is a simple step that releases quite a large amount of free space; let me explain with an example. Suppose you have downloaded a lot of movies on Netflix, but you forgot to delete them. What will happen is, it will occupy some space on your device. So, when you clear App Data, it not only clears the Cache but also resets the application, meaning you’ll have more space in storage. But you will have to sign in again on Netflix. Follow these steps to Clear App Data:
How to Clear App Data:
Step 1: Open the Settings application on your device.
Step 2: Head Over to Apps Menu
Step 3: Choose Installed Applications
Step 4: Find the Application you want to Clear the App Data of
Step 5: Select it, Move to the Storage Tab
Step 6: Hit Clear Storage/Clear App Data
Note: The Next time you open the application, you will need to download all the resources from scratch. For example, if you clear the App Data of INDUSTRACK Mobile App, you will need to download the app again from the Play Store.
