@Min_Liu @muchisx my apologies, you are right in saying that this is a breaking change. I was simply trying to provide info about the workaround (which is not ideal, but is the best option that’s available for the time being). In reality, Shopify definitely should have done a better job of providing us with advance notice before rolling this out.
@Alan_G while I’m not expecting Shopify to fully revert to the old system (if Shopify is in fact trying to prevent app developers from getting free access to paid plans/resources from other devs) then perhaps there should at least be a possibility of installing your OWN apps on your test stores using a test charge on real plans
