If you want to continue to use Instagram you need to change your content strategy to incorporate more video such as Stories, Reels, Lives/IGTV.
You may have to experiment with your posting schedule and content calendar. If you currently post 5x a week with photos only, you may have to try experimenting with 3 Reels a week, 1 IGTV and 1 photo post.
You can test this over the next few months as Instagram makes their changes. I will be changing up my strategy and will keep you posted as time goes on!
I can understand how frustrating it can be to create video, edit, film etc.
