Make sure to change the app client id, app client secret for the production in your code. And login with the credentials of one of the users under your production account.

We did all that. Case: 17947263 details the error.

What is the error. I don't have access to support cases.

Unfortunately, I have to delete your last post for the following reasons:

1. The content is not formatted in a way that it could be easily read. No lines, no paragraphs.

2. The post contains your app sensitive info such as both app client id, client secret and phone number.

3. Redundant info such as the JWT which is not the grant-type of the concern app.

I also asked for the error and see no error in the post.

I have to delete the new post again. The same problem as I wrote earlier.
