I have a half-dozen investment accounts at two different brokers. I updated them using the normal update process. Both accounts at broker A updated correctly. three accounts at broker B updated correctly but one simply deleted all transactions since January 10, 2024 and didn't load any new ones. The account was migrated from TD Ameritrade many months ago and has about 15 years of data.
Any ideas (1) why this happened and (2) how to fix it. Help is greatly appreciated.
