Hello @Kevin K
you for reaching out on the community and telling us about your issue. .
I do apologize for the issue you're having. I'm wondering here what's causing the issue. Are you and your wife on separate logins for your bank accounts? If so it should separate them still even if you're sharing a different account together. I'm wondering here if we might be able to get your account into Quicken by downloading it from the website then importing to Quicken. From there if we are able to do so we can also try connecting it to Quicken for download. I'll leave steps down below on how to do so.
First we'll want to try importing the QFX into Quicken The article will show general bank website steps to help us find the QFX download.
Once you have the account imported into Quicken you should be able to activate it for download with the article down below.
Once you get the chance to try this let us know if you're able to get the downloads working. If not we can see what we can try next.
