Hello @William McLachlan
Thank you for reaching out on the community and telling us about your issue. I do apologize for the issue you're having. It sounds like the cash may not be included in the download from wealthscape. This may be something that you'd need to talk about wealthscape with as they're the ones who control what is imported into Quicken with it being direct connect. Another thing that may also work is making a manual adjustment but then you'd still have to do this occasionally since it's something that changes consistently.
My last guess would be to maybe check to see if any transactions might indicate the cash is being downloaded but not put in the proper place but I believe you've already done this. In any case please let us know what you can find out and we'll see if we're able to do anything.
Thanks,
Quicken Francisco
