Hello @JNickels
Thank you for reaching out on the community and telling us about your issue. I do apologize for the issue you're having. If you wouldn't mind could get get some more details on what exactly is going on. Do the transactions disappear after opening the program or when you try updating the accounts? Is there any sort of trend what transactions are having issues or is it at random? Has this been a more recent issue or is there a specific patch this has been happening?
Once we're able to get some more details we'll be able to see what we're able to try. Let us know once you get the chance!
Thanks,
Quicken Francisco
