It looks like you don’t have any Instagram Business accounts connected to your Facebook profile. This is confirmed. We checked all the Pages you granted access to, as well as all Instagram accounts linked to them, and found nothing.
We recommend that you switch your account to a Business or Creator account — this will significantly speed up comment processing and make it easier to manage your clients’ accounts (for example, if you are an SMM specialist).
If you have already switched your account to Business or Creator but still see this message — remove our app here and here, then authorize again.
