A great example of this is AWS. I'm not a power user but I dabble. You have to go back and forth through user docs that all have some % of the correct steps, but no single doc has all of the correct steps. Some reference deprecated api, some just never seemed to work in the first place and you wonder how it even got there.

I get that these ecosystems evolve over time but I'm not convinced that that evolution requires inability to use the underlying features effectively.
