I'm planning to publish an application using the Google OAuth 2.0 consent screen with sensitive scopes.
In the FAQ under Preparing for verification by creating a video it states
show the OAuth grant process that users will experience, in English
The application is only in German and intended for use in German speaking regions (for now), therefore everything in the application is in German.
My question is, do I have to translate my whole application to English, or is it enough to simply switch the language in the OAuth popup to English?
Also, how would this effect the links to the privacy policy, homepage and such. Would they also need to be translate from German into English?
I tried to find more on that topic on the official FAQ page, through a Google search and here on SO. Sadly to no avail.
