I am facing some weird issue in Shopify app development. I have created app which is working fine on Development store. it is able to add some data on development store.
But for testing purpose I have offered this app to the merchants to test this app on their live store having activated Shopify Paid plan. But app can not add any data. Post/Put requests are auto converted to Get requests.
I have created couple of apps those are published on App store and in past they were being used by Active Paid Plan merchants before app has been published without any issue.
Is there something changed on Shopify side. or I am missing something this time ?
Any help will be appreciated.
