You seem oblivious to the fact that much government control is in the hands of non-elected bureaucrats. She was president on paper only but probably couldn't have ordered a chicken sandwich from the WH kitchen without staff approval. More simply put, you might view her as president for an hour or so but few others did, especially in DC.
No, she was never the president but still just the Vice president doing what a vice president is supposed to do and that is filling in for the president during times of illness. Her title never changed just her duties in case of a critical national emergency. In reality, nothing changed as Obama was conscious and still running the country.
I was just reading that a few days ago, Harris’ communications director resigned, and now the communications director for the White House has also left her position. Makes you wonder what is going on behind the scenes ? https://www.yahoo.com/entertainment/white-house-communications-director-leaving
