Damn instagram these greedy shts. Limiting organic reach after ads is such a shity move.
Me and some others had similar experiences writing about this.
I have done this on my main account about a year ago without knowing of the reach lowering effect and grew pretty well but soon noticed that I wasn’t growing orgsnically no more.
For me it took some time not doing any ads, boosting my posts with powerlikes to get suggested to more and more people and organically growing my account to get it back to normal but I still don’t know if it is 100% back to normal again.
Also switching back to a personal profile might help reset this after a while. See here:
Also @embraceone and me have had Threads on this exact issue, maybe you can find something of value:
