I have a verified app and I would like to change the OAuth consent screen application name(only application name).
In order to do this, it seems that I need to reverify this again, but my app is ALREADY in production now, if I submit it for verification would the current verified OAuth screen suddenly be shown as unverified, OR is there any way to show the old OAuth screen until the new one is verified ?
You can always re-apply for verification at any time. The previous approved state of your app will hold.
