Sometimes account transactions can be missing from Cloud Feeds in Core because of incomplete downloading of the transactions from the bank. In case of missing transactions, the first step is to refresh your feeds. If your login information for the bank or financial institution has changed, update the credentials. If this doesn't help, contact BQE Support so that we can troubleshoot the issue by triggering a refresh in the back-end or opening a Yodlee support ticket.
There is an option to disconnect and then reconnect to your account; the missing transactions can show up that way. However, note that if you disconnect the accounts, you will lose all existing links. Check Core Help Center for details.
