App disconnecting after POP confirmation

[KonssnoK]

App issue for: https://github.com/espressif/esp-idf/issues/8739

• Development Kit: ESP32-S3DevKitC
• IDF version: v4.4 https://github.com/espressif/esp-idf/commit/c29343eb94d2f2ca17b3a5b38c82452e556147f2
• Using wifi_prov_mgr code
• IOS app 2.0.14

After inserting POP "abcd1234" in the app and pressing the button the communication gets dropped, and the device restarts advertising.

By doing some digging in the device code the connection gets closed by ESP_GATT_CONN_TERMINATE_PEER_USER.

it comes out this was happening because Encrypted communication was not selected in the settings. Selecting the option solved the issue. :) (Still, you have to press pair twice to finish the provisioning).
