Hi, I have developed a theme app extension. The issue I’m facing is that the Preview URL as well as the URL generated for a custom distribution method, don’t install the app on the store, but instead take me straight to the default app page
I’m having this same issue on the same day as you, actually. Also, the default url redirect (https://shopify.dev/apps/default-app-home/api/auth) returns a 404. Have you had any luck about this yet @btimfl ?
To resolve this issue, you need to add the required scopes in the shopify.app.toml file. By default, this file may not include the necessary variable for scopes. Before installing the app, ensure you add the scope variable with the access permissions you want for the app.
After adding the scopes, update them by running the command “shopify app deploy”
I faced a similar problem, and this solution fixed it for me just after added below lines.
[access_scopes]
scopes = “read_checkout_branding_settings,write_cart_transforms,write_checkout_branding_settings”

Thanks!
