How to get more reach on IG?

Instagram is incredibly annoying! I don't understand anything about the algorithm anymore if it's even the reason for my posts not reaching anyone new or even 3/4 of my followers! The hashtags don't even work in the way they used to either. Threads feed is messed up causing no one to be able to view my work. I don't know what to do? How to I get more people to see my art on IG?I haven't stated a shop selling my art yet but I am planning to soon. I'm trying to post every 5 days and see if that helps me. So far no luck with that either. Does anyone have any advice? Should I try the Cara app and see if that helps me with getting new reach on IG? My account btw is @/artofzahrasarfraz
