When does The Lion Guard return?

The Lion Guard is an animated children's television series based on 1994 film The Lion King. The first two seasons take place within the time-gap in the 1998 film Simba's Pride. The lion Guard is a group that serves to protect the circle of life, traditionally led by the second born of the King and Queen. The majority of the third and final season takes place in parallel with the film's second act.
The show centers on King Simba, his wife Nala and their two children Kiara and Kion; who as second-born to the throne has been gifted with a power called the Roar of the Elders. Despite tradition that the Lion Guard has always been made of lions, Kion appoints his friends Bunga the honey badger, Beshte the hippopotamus, Fuli the cheetah, and Ono the egret. They set out to keep their homeland safe and protect it from animals who disrespect the Circle of Life.
