Unpairing your register removes all cache and locally stored data. 

If you’re looking to fix repeated sync errors, missing data, or app crashes then you should reset your register instead. 

To unpair your register: 

1. Open the Register app on your device 
2. Select More
3. Select Unpair Register 

After unpairing your register you’ll return back to the initial pairing screen, ready for setup. 

Keep in mind, you must have the right permissions set to be able to unpair registers.
