I call Editorial Mistake #4 "the George R.R. Martin Effect" because Game of Thrones and works like it have made POV shifts very popular, especially among my sci-fi/fantasy clients.

In GOT, it makes sense. Martin has a broad cast of characters carrying out a geopolitical saga over three different continents. This leads to a slow burn that assumedly will end up with all of those perspectives converging in one place as they fight for control of the Iron Throne.

This is the reader’s reward for slogging through all the weird names and mysterious backstories: seeing how beloved and reviled characters will interact with one another.

There are some downsides to POV shifts, though, that you should keep in mind for your own writing.
