P-NUCLEO-LRWAN2 sensor board - problem with all-zeros AppEUI.

I just got my P-NUCLEO-LRWAN2. I'm able to get the gateway running, but I'm facing troubles with the sensor board.

The NUCLEO-L073RZ should already be flashed with firmware that reads EUI parameters from the I-NUCLEO-LRWAN1, and I was able to read the correct DevEUI key from memory 0x08080000. However, the AppEUI key at memory 0x08080008 shows zeros only.

I tried flashing the NUCLEO-board, with the AT_Master project including code-snippet:

 /* Set AppEUI */
uint8_t AppID[8] = {n7, n6, n5, n4, n3, n2, n1, n0}; // nx=bytex
uint8_t *PtrAppID = &AppID;
LoRa_SetAppID(PtrAppID);

but still no luck. Also, I've tried enrolling a device with all-zeros JoinEUI in the Loriot sample application but that did not work either. Am I required to use the AppEUI from the sticker of the package ? Should the LoRa_SetAppID() function call be sufficient to update the AppEUI at memory 0x08080008 ?
