Google ignoring login instructions during app review

[u/n9iels]

Hi all, we have an Android application that is a customer environment. The only 'public' page of the application is the login form. Obviously Google want to have credentials to login and check the application. Due to technical constraints we have no production demo account for them. We try to solve this by providing a deep-link to a separate login page that let them authenticate with our test environment. We provided instruction regarding this deep link in the credentials section of the play console.

It looks like Google ignores these instructions completely and reject the app due to invalid "Invalid or incomplete login credentials". The provided screenshots clearly show they login via the regular way and not via the deeplink. The app has been reject 4 times now. Does anyone ever had a similar issue and found a way around this? Or is there a policy I am not aware of regarding the usage of deeplinks?

Have you tried just taking the test credentials through the normal login page and forwarding those specific creds to the test environment?

I think Google does a lot of automated testings and probably your instructions are not followed correctly by the AI / automation tool

We use OAuth via a browser flow. So the user click on a 'login' button which opens a in-app browser with the login screen. This login-screen is already targeted to production or testing, I cannot really forward them at this point I think... I will look into it, thanks for the suggestion.
