Nevermind, I was able to resolve this issue by updating the plugin to the latest version.
@sputas1111, try updating and see if that works for you too.
Hi @andrewmrobbins,
I’m experiencing this same issue. After disconnecting the app, I tried to reactivate it and got the same error message about the storefront access token.
I tried creating a new Shopify private app, but no luck. And I’ve been using the “copy to clipboard” option as well.
