The main issue is failure to download transactions. Sometimes deactivating/reactivating will fix it for a while. However today it wouldn't resolve it. I switched to EWC and everything downloads fine. Not sure what the push is to use DC, unless it is to facilitate using their bill pay system (which I don't use).
So how do I escalate this? Previously I worked with First Tech. They reached out to Quicken. I then received this in an email from First Tech tech support:
Quicken has acknowledged a problem on their side where there is a data file issue that is affecting First Tech accounts specifically. To resolve this issue, Quicken has been able to guide members thorugh a process that involves generating backup data files, which helped correct the downloading issue. After that, they relinked the Quicken accounts to the corresponding First Tech accounts.
I reached out to Quicken phone support and they had procedure or guidance. I then changed my connection from DC to EWC and all is good.
