Upgrade Meta SDK version with a lot of conflicts

Hi all,

Since ~2020, I've been using the Meta (Oculus) SDK tool to create a Virtual Experience on Unity.
But recently I had a very frustrating experience. In my development process, I faced some deprecated features which are replaced by another, that didn't work.
(E.g. "Throw when ungrab" feature from the Grabbable component)

I decided to upgrade my package from the 66 version to the 68.
Now I have a lot of errors and warnings. My app doesn't function at all.
Why don't you leave some components with the "Deprecated", or "Legacy" tag, and suggest what is better to use instead?
I even can't use your own prefab "OVRInteractionComperhensive", as it has broken scripts.
Also, the documentation is deprecated, because it is related to the oldest version of SDK.

Should I downgrade SDK back to 66? Or maybe someone faced with more nice solutions?

Unity version: 2022.3.32f1

Thanks in advance and best regards.
