I have installed a custom application in my Shopify store. uses an access token for authorization. it works fine for a day. after a day with the same credentials, it return 401 unauthorized.
It gets fixed when I open my custom application from the admin panel using the Apps section on the side bar. but after a day faces the same unauthorized issue.
I used @Shopify_77 /koa-shopify-auth module for authorization.
Is there anything in the store configuration that I need to double-check? Is there something else to do to drill down on this issue?
