Hi @sandral18706,
Outages are, unfortunately, an inevitable issue. A tool that I’ve found helpful is this post:
If you have issues not addressed there, I would recommend contacting Tiller Money help instead of the bank. In most cases, the financial institutions don’t really worry about how their changes will affect syncing with products like Tiller, and sometimes make changes that break the connection. Unfortunately that means outages happen, but if you let Tiller Money know they can work to correct the issue.
In your case, on that post I linked to it looks like Capital One requires two-factor authentication. If you got to tillerhq.com, log in, then scroll down to the accounts list you should be able to re-login to any bank account there. Hope this helps!
