Why was aunt be a not on the later shows of Andy Griffith?

Aunt Bee, portrayed by Frances Bavier, was a beloved character on "The Andy Griffith Show." However, she was not featured in the later series, "Mayberry R.F.D." due to Bavier's desire to step away from the role. Additionally, her character's storyline was wrapped up when she decided to stay in Mayberry rather than move with Andy and his family. Bavier's absence allowed for new characters and storylines to emerge in the continuation of the show's legacy.
