I'm going to echo a lot of people's response here, and say that your best bet is to reduce and/or eliminate your dependence on Amazon. As far as IG, I think that it's a channel worth pursuing because your product fits the platform so well.

Just an idea: you mentioned that you had a successful Kickstarter in 2014. If you still have the list of backers, and their emails, this is a good opportunity to start an email list, and tell your story to them. The primary goal will be to tell them why you're not on Amazon, and on IG, and how it happened.

It is an opportunity to also direct them to your new selling channel (or tell them that you are working on one). You can also appeal to your customer to lend your their support (I don't know how, but it is a good opportunity to figure out how that support could look like).
