When I go to https://www.instagram.com/explore/tags/ I just get a “Sorry, this page isn’t available”. I’m guessing this is an indicator that the hashtag is banned by IG?
However if I put the same hashtag in hashtagify it does show 35.7 popularity 
Are you even typing in the hashtag?
for example : https://www.instagram.com/explore/tags/lol/ works just fine
Ah, the forum edited it for some reason or I made a typo… what I meant to say is when I go to https://www.instagram.com/explore/tags/myhashtag (not “hashtag” per se obviously, just using “myhashtag” as a placeholder.
