Does posting 2 or more trial reels and posting contents in IG 2x a day lessen your views?

I had this client where her trial reels views became only 1 or 2 digits whenever posting trial reels nowadays. I noticed it started when we posted 2x a day in her IG. Does the audience become saturated because of this? Most of her contents are talking video 1-2 mins long and there are also reel contents (educational and trendy)
