Hello @stacyh01953
Thank you for reaching out on the community and telling us about your issue. I do apologize for the issue you're having. I'm wondering here what might be causing the issue since it's been happening now for almost 2 months here. I'm wondering if we may have some better success if we try adding the account as if it were a new account then linking rather than reconnecting it. I'll leave instructions down below on how to do so.
First thing I'll recommend is to save a backup to revert back to just in case. You can find how to do so down below.

Next we'll try deactivating all of the accounts for the affected FI. You can do so by following the article listed down below.

Once all the accounts are deactivated go ahead and follow the article here on reconnecting the accounts.

Once you've had a chance to try this let us know if you're able to produce any different results. If not we'll see what we can try next.
Thanks,
Quicken Francisco
