A question was asked from John Mueller of Google that “Does a canonical chain result in the loss of page authority as a redirect chain does?” On this Google’s John Mueller responded that “We don’t have a notion of page authority.”
Here is the tweet & the context the way why John reverted:
We don't have a notion of page authority.

Last week John added “there’s some signals that we can’t reliably collect on a per page basis where we do need to have a bit of a better understanding of the overall site. And quality kind of falls into that category.” And now john says about the Page authority.
So, it becomes quite hard to completely understand these topics, the statement from Google about Page authority & quality & how Google regulates the conception on a page.
