About 12 weeks ago my engagement dropped by about 50% overnight. My account is a real business, selling a real product in a fairly popular niche and was growing organically (with some give aways sprinkled in). I know my audience well and I know what pictures should get better response than others. I have tested with everything I can think of. My account seems to be throttled or something because all pictures get a very similar amount of likes. The likes also seem to come in batches, a whole bunch at once, then nothing, then a bunch more. I have some evidence that my pictures aren't showing for all of my followers. Is there anything I can do to fix the account? I've tried contacting instagram several times with no response. Coincedentally this happened almost exactly when I moved into a new city with a new internet provider and stuff. I''m trying to think of anything that could have caused it. There are other accounts that I know the owners of and some of them are having a similar issue and some are not. Can anyone please help me?
