By any chance, did she sign up for creator fund or that program that pays creators?

TikTok purposely lowers those who joined the creator fund program, so they can save money, since they pay by view count. make sure to check with her, and by any chance if she did, make her quit it. the fund isn’t worth it. it’s a couple dollars for a thousand views. she can earn more everyday by working at McDonalds than getting a video with a viewcount of 500k
