gives a message, registration identifier couldn't be found in the cache

Hello! It sounds like you're encountering an issue with the NBE app where the message "registration identifier couldn't be found in the cache" pops up. Let's see if we can resolve this together.

To start, could you please let me know if you have already attempted any troubleshooting steps? For example, have you tried clearing the app's cache or data? This is a common initial fix for issues like this.

If you haven't tried that yet, here’s how you can clear the cache and data for the NBE app on your Android device:

1. Open the Settings App on your Android device.
2. Scroll down and select Apps or Applications.
3. Find and tap on the NBE app from the list.
4. Select Storage.
5. Tap on Clear Cache and then Clear Data. (Note: Clearing data may reset your settings in the app, so make sure to have any necessary information saved before doing this).

After you’ve done that, restart your device and try activating the soft token again.

If that doesn’t resolve the issue, or if you’ve already tried this, please let me know, and we can look into some other causes or advanced troubleshooting steps.
