Resetting your register can help fix repeated sync errors, missing data, or app crashes. 

If you’re looking to remove all cache and  locally stored data, then you should unpair your register.

To reset your register: 

1. Open the Register app on your device 
2. Select More
3. Select Reset Register Data 
4. Select Reset

After resetting your register, you’ll return back to the initial loading screen or login screen.
