I am writing my first mobile app on Android Studio Electric EEl (2022.1.1 Patch 2).
For my first app, I would like to develop a simple checkbox that allows user to toggle the Bluetooth ON/OFF. The project can be accessed here if: https://github.com/krupis/BLE_test_app
I have pretty much followed the tutorial by Android Codelab on youtube, just with changed some variable names and other small things: https://www.youtube.com/watch?v=oZKd6gpMKQg&ab_channel=AndroidCodelab

I have connected my physical device (Samsung Z Flip) to my PC via the USB and I am running my APP on my physical device.
When the APP is launched, I can click on the checkbox to Enable the Bluetooth. As soon as I click the button, the prompt shows up at the bottom requesting to give access to enable the Bluetooth. I click "Allow" and I can see that the Bluetooth is enabled on my phone
However, when I try to toggle the checkbox again (Uncheck it), I can see that the the correct lines of code are executed because I can see "Disabling the Bluetooth" being printed to Debug window. But the Bluetooth does not turn OFF after I call BA.disable() for some reason.
Debug logs:
