Problem logging into FirstTech when using also using Mint/Personal Capital.

Does anyone have an issue that when their information is updated in Mint, it basically locks them out from logging into their site directly?

I get the "unrecongised device" challenge, but then when I run through this process, i get the dreaded "There was a problem submitting your request" error.

Trying to resolve this with the team for over a year since they updated their backend security however no luck.
