App still lacking after recent update

I understand the app is still in development, but the fact that this is an app only bank (not even an online banking platform) makes it very difficult to look past features that the app still lacks. Especially the features that are already written in the terms and conditions, but are yet to be implemented.

For me, personally, the biggest one is the authorized user feature. Me and my wife use the account as our joint spending account, but she can't access any of our accounts apart from the credit card. And as she is in charge of our budgeting, this is a major problem.

I have asked about this feature before and the only reply I get, is that it will be implemented soon. You guys seem to update your banking app only about once a month, and now that the recent update is out and it also didn't have this feature, we are getting a little impatient.

All of the other banks would make it very easy for me and my wife to have access to one bank account, so please step up, or we will have to move.
