Answer:
Season 4 is slowly being published in the United States but on Disney plus. Disney Plus has gained ownership of the show over Netflix so season 5 will appear on Disney Plus as well. Season 5 is set to premiere this summer of 2022. Each episode will probably be released one by one, most likely in a random order like season 4. Although you can still watch seasons 1 through 3 on Netflix for now. If you want any of the new seasons like 4 and 5 you will have to watch them on Disney Plus.
