Why aren't my hash tags on Instagram working like they did before?

Okay, so I put hash tags on every picture I have on Instagram and it used to get as much as 50 likes and I would get a ton of followers. For about a week my pics aren't getting as much likes as they used to. It's so annoying. Do I change my hast tags? Do I re-install the app again? (By the way I have an Iphone) (My profile is not on private).

Maybe people just don't like the pictures you've been putting up lately.

I've been having this same exact problem. My guess is that people aren't on instagram as much as they used to be, since it's summer vacation and all. The tags could also be replaced by other tags, but the ones I put are usually enough. I don't know, try putting more than one set? After you get as much as you can from those 30 tags, get different ones and copy and paste them. That's what I'm doing.
