iTunes Connect - There was an error creating your Bundle ID

I'm trying to set up my first app in iTunes Connect so I can submit it... and I go through the whole set up process of entering metadata, and when I go to save on the last screen I get this error:

There was an error creating your Bundle ID.

And it won't let me save it. To clarify, I'm not even to the point that my app can be submitted, this is the app setup before you submit.

I'm not understanding what's going on here. I created the certificates, bundle IDs and provisioning profiles correctly, and the bundle ID I'm using shows in the bundle ID dropdown on the first page, etc etc. As far as I can see nothing is wrong, yet it won't let me create the app.

I already went through, deleted my previous bundle IDs and all that, recreated them, and still it gives me this error. I searched around and couldn't find any information on this. Anyone have an idea why this might occur?

Solution

This worked for me. You can register the new App ID from your developer portal - Certificates, Identifiers & Profiles module. Then create your app in iTunes Connect again with selecting existing app ID you just created. Good luck.
