We need to note that our team is not able to make any changes to the Version-Live of your application. Moreover, we can’t make changes to your version-test of an app and deploy it further.
As it was noted, your button was not visible even on the version test, but this is related to the Responsive Design of your application. So, you just need to place the button in a way it will not be collapsed by other elements and groups.
We changed a bit the placement of the element in order to test it.
But allow us to note that the issue is related to the link in your Apple Dev. Console, since it seems like you changed the link there.
Please share the screenshots of the redirect URLs from your Apple Console, so we will define exactly what was changed.
Also, we need to note that immediately after we accessed your application on the version-live, it was proposed to download your native application. We did it, however, there is no Sign In with Apple Button in your application. Unfortunately, we can’t fix this within your native application (since it is wrapped with a third-party service).
Looking to hearing from you soon.
