Characteristic not updating after moving it to app stackhttps://devzone.nordicsemi.com/f/nordic-q-a/70941/characteristic-not-updating-after-moving-it-to-app-stackHello, I hope you are doing well. I am using the nRF52832 with the SDK16. After adding some new custom characteristics, I didn&#39;t have enough space in the BLE_GATTS_VLOC_STACK, so I moved the characteristic data location to BLE_GATTS_VLOC_USER.
