Since the latest update recent transactions from most or all accounts will disappear when restarting Quicken. Thinking it might be OneDrive related, I moved the qdf file to C:, but it happened again today. File Validation doesn't resolve, though it finds a ton of errors (most look like the same ones from prior validations). Fortunately I've started backing up daily. This is at least the 5th time it's happened. HELP!
