After using 1Password to log on to TD Bank for several years, now it is not working, and your recommended steps above also do not seem to work. And I have no idea how to get it to work.
I split your post from that other sprawling thread in order to give you the personal attention you deserve. I hope you don't mind. Here are the steps I just performed (again) to get a working TD Bank Login item.
Using the above technique I was able to save and fill a sample login at:
Manually saving a new Login can be useful for logins that are either problematic to begin with or were once working but have since stopped. Saving a new Login item allows 1Password to refresh everything it "knows" about the page. Login pages often change as websites are updated and this can be a necessary but very useful tip.
If you are still having trouble, please try disabling autosubmit for that Login and let me know if that resolves the issue. It looks like autosubmit may need to be disabled, but I don't have an account there. I was not able to verify autosubmit because of this.
I hope that helps. If you're still having trouble, could you please describe in as much detail as possible the steps you are taking, and what you are [not] seeing happen? With some additional information from you we can then provide you with specific assistance.
