Is there anything left for me to do?

I ran across one of my kids teachers on tiktok. It's my 8th graders teachers and I only remember her specifically because she also coaches cheerleading that my 6th grader is in. She was doing a dance and while the dance wasn't inappropriate, I felt the song was. I don't know the exact song but the tiktok was her saying her students before the state writing test and she just looks annoyed and very low energy and the song said my back hurts my bras too tight my booty shaking from left to right. Then she said them after the state writing test and she dances more high energy to the same lyrics and while again she wasn't dancing inappropriate I feel she could have picked a different song. I brought it up to the principal and showed her the tiktok and she just kind of looked at me funny and said "O... Kay..." I thought they would at least talk to her but every time I go to her page the last 2 weeks it's still been up. So maybe they didn't talk to her? Is there anything left for me to do or do I just let it go?
