How do I register Cubasis 3 in My Steinberg?

Like the subject says.

I’m on iPad, I have Cubasis 2 & 3, bought them when they where launched. Only 2 is registered in My Steinberg.
All plugs have successfully migrated from 2 to 3.
They are on separate iPads but bought with the same Apple ID.

Hi Marshall,

Thank you for your message.

We are aware of registration issues, which are currently evaluated and hopefully solved in the next Cubasis update.
As mentioned, transferring previous in-app purchases from Cubasis 2 to Cubasis 3 is unrelated to the registration topics, and will work as expected.

Best wishes,

Thanks Lars!
