The FirstBank of Colorado connection has now been down for at least 24 days. The bank tells me I need to check with Quicken but I'm starting to give up hope that this is going to get resolved. I count on this connection for both business and personal accounts and if it's not ever going to be fixed, I need to start taking steps towards a new bank or platform. This seems like a really long downtime, now closing in quickly on a full month. All I get from the below is that it's being investigated but that's been the case now for more than 3 weeks.
