Hi everyone!
A friend of mine asked for help, her reels have been reaching fewer and fewer people over the past two months. I checked and her reels are not displayed by hashtag search, I guess this is a shadowban. But the point is that her other posts are not shadowbanned, only her reels. She only posts original content, uses 5-6 different hashtags per reel, does not use any third-party apps, no automation, no inappropriate content.
Any ideas on how to fix this would be much appreciated 
Could be a variety of factors. Maybe check the hashtags that she’s using
Is she using always the same hashtags?
Even if your friend uses hashtags, her post won’t necessarily appear in the hashtag search and this happens to all kinds of posts not only for reels.
