Hybrid app authorization inconsistent



we have two apps configured in sellercentral. Both are hybrid apps (MWS + SP-API). One is already published, the other one is in draft. When testing selling partner authorization of our app we came across an inconsistency. We generate both authorization links like this:


and in case of the draft app we append &version=beta.

When visiting the authorization link for the app in draft status it shows the page on https://sellercentral.amazon.com/apps/authorize/consent, listing the different access the application will have upon accepting the form.

When visiting the authorization link for the production app it redirects us to https://sellercentral.amazon.com/gp/mws/registration/register.html, showing the old MWS authorization form with the Developers name and ID.

The only diffence i could think would cause this is the lack of Oauth URL and redirect URL in our production app config in sellercentral. Can anyone confirm or deny this? Will it start working the correct way once we fill in those two fields?

Best regards,
