There are a lot of posts about how Fidelity sweeps into core funds are causing users to create transactions to cause accurate data. I haven't seen any comments about how a "mySmart" account has had superfluous transactions created or how [at least as far as I'm concerned] a mySmart account is just a checking account and trying to make an EWC connection to that account forces me to treat it as Brokerage with $1.00 FDIC funds that each have their "dividends" rather than allowing me to treat that account as Checking where the "dividends" are simply "interest" that happens to come from multiple sources.
My mySmart account has never been an investment account to me. I don't care which FDIC insured bank holds my "cash" balance or pays my "interest".
I gave up trying to correct my "shares" with Added/Removed transactions to have an accurate accounting of "my cash on hand" and changed my core positions to a single fund. Maybe that will get rid of all of the warning message about the bank reporting different shares on multiple FDIC funds. Hopefully it will at least reduce the number of manual transactions I have to enter to treat this account as a "basic checking account".
Hopefully EWC is going to eventually recognize that my mySmart account is just a basic checking account. Funds be damned!
