Yes. And it's not because school started or whatever. it's because algorithm has changed. Instagram has done something really bad so they fucked everyones engagement. I've lost alot of views on my page, same as a lot of people that I talked to over Instagram (that have 100k+ pages) or through reddit.
Insta has done something so they fucked us everyone. Literally. All you can do is wait, and wait.
I have a page 20k followers, had 1,7 mill impressions on 4th of january, now its around 500k or even less. Discovery was 800k, now its 200k and its going down really fast.
