Recieving Messages that we Need to Upgrade to NEW GraphQL However Developer Says we are not using the Old Standard

I’m not sure where to go next. We keep getting messages from Shopify that our app will be demoted. However our developer says we are not using the old standard. Can anyone at Shopify confirm if our app: easy image overlays, is actually using the old format?

Or can anyone on the forums recommend a developer I can get to take a second look at this?

Thank you for any help!
