Picamera2 versions apt or pip

Picamera2 comes with Bullseye as default. Official Picamera2 manual says to not to use pip to install Picamera2 but to use apt to avoid incompatibility errors. I now have two different Picamera2s, one installed as default and the other apparently installed by your setup using pip. During update && upgrade it reads now that the upgrade can not remove the other installation. Can you please explain how to resolve this confusion and which Picamera2 version will your example codes use.

Yeah, we need to update it in case to mislead other users.
