I understand the route you are trying to take me. However, the problem persits across all platforms (desktop PC, Mac  laptop, my android phone, my wife's Apple phone). So, it's definitely not a cache issue. It's also not a slow running app issue, either. I never said it was running slow. The problem is: My legacy (older) records (both estimates and invoices) literally disappear over a specific amount of time. Is there a setting that I can use to cause QB to keep them indefinitely?
