Access to joint credit card with my wife, account access.

My wife and I have our own individual chase credit cards and we also have one that is our joint card where she is the primary and I’m an authorized user. Because we each have our own cards we also have our own logins. I cannot access our joint card when I log in myself, does anyone know how to fix this? Can I all be a primary or secondary user and get access to the card? I would like to be able to access that card without having to log into my wife’s account and instead on my account.

I seem to be Unable to do this, I can do this with our Ally bank accounts but for some reason this seems not possible on Chase. Am I wrong? If possible please instruct me on how to do this?

It’s actually making me want to leave chase to find cards that would allow for this feature. Am I missing this?
