Thank you for
reaching out on the community and telling us about your issue. I would recommend deactivating and reactivating the Schwab accounts since no new information has downloaded since the start of the year. Can you save a backup before doing this. Once that's done go ahead and follow the steps to deactivate and reactivate each of the accounts. Make sure to do all of them at once so you're able to relink them all at once.
Please let us know
if this helps resolve the issue for you.
