Hello @1captainj,
Thank you for reaching out to the Community and telling us about this issue. I'm sorry to hear you're running into this problem. Those screenshots are from Quicken for Mac; it looks different in Quicken for Windows.
Before changing the connection method, there are other things to check first. Is having several days worth of transactions go missing a recurring issue, or did it happen just once? Have you verified that these transactions are showing as cleared with the financial institution (pending transactions don't download into Quicken)? Are these transactions over 90 days old? Have you checked the account register to make sure that it is sorted by date and no filters are active (in case the transactions are there, but hidden)?
Thank you.
