A check-up will hurt no one; in the application, swipe left for the options to show and select the ‘Driver Status’ option.

The only and easy way to check whether the driver is in perfect working condition would be to check the NEON Enabled: Yes, the second line in this popup.

If the NEON Enabled reflects yes, then you have done everything correctly while installing; and if it reflects no, then you might have to start over.
