Delete the cache and data in PAX devices.
Clearing the cache of the Handpoint Payments app can be helpful when the reader has been acting strangely and going through different changes for troubleshooting.
This will erase the configurations from the app in your reader, clearing out any app related data. After performing this step, it is necessary to setup the app again (eg. go through the onboarding)
To clear the cache and data:
Navigate to the Android settings of the terminal (not the app)
Use password pax9876@@ or 9876 when required
Go to the Apps section
Locate the Handpoint app (or the payments app you use)
Go to Storage
Select CLEAR DATA (this will clear both cache and data)
