notify not updating values in nRF Connect

[Gibbz]

I'm trying to get my ble notifications to auto update on nRF Connect android app.
Ive selected the button to subscribe to notifications in the app.

I'm unsure if this is a bug with the app, my code, or the library. Basically I have the following snips of code. I assume this is all I need to do to get it to work?

Set characteristic

  trip_duration_characteristic = user_data_service->createCharacteristic(
                                         (uint16_t) 0x2BF2,
                                         NIMBLE_PROPERTY::READ |
                                         NIMBLE_PROPERTY::NOTIFY);

Apply a value, and notify

    trip_duration_characteristic->setValue(value);
    trip_duration_characteristic->notify();

Your code looks fine, could you set the log level to debug and share logs of the notification being sent?
