After clicking "Update Accounts", it completes without any errors. The usual red flags are shown next to the accounts with new transactions. However, when I go into the accounts with transactions, there are no "Downloaded Transactions" shown. This occurs for my checking account and several different credit cards with different banks. (Apparently there were no new transactions in the last week for my investment accounts, so I don't know if it happens there as well.)
I checked one of the credit card's website & the checking account and there were indeed new transactions, so it's not just an erroneous red flag. Since this occurs with multiple (4) institutions, it looks like a Quicken issue, not the banks.
I tried exiting and restarting Quicken. I tried redownloading. (Neither worked.)
I'm running Quicken Classic on Windows 10, R54.9. This worked last weekend and I believe an update was installed sometime this week. (I hesitate to include a screenshot because of the amount of personal information it would include.)
