[UPDATE: The banner has cleared itself. Apparently, I should learn a little patience? Original post follows.]
I changed the password for the site and 1Password has the new password stored (by way of 1PW recognizing my activity of changing the password on that site through my browser). It seems to me that the warning message should be cleared automatically upon 1PW storing a new password for the site. Failing that, it seems to me there should be a way to clear the warning message, so I don't see it, say, a month from now, and wonder about it. Apologies if I'm missing something obvious in the interface or on this support forum.
