Some feedback I would like to provide. Can you please suggest changing when a missing cost basis error is reported. I generally sync transactions to CL shortly after making them, so it can be frustrating when missing cost basis only gets highlighted when the calculated cost basis is negative, but in addition to that, it could lead to tax implications if the basis is missing and not fixed for over a year because it wasn't highlighted at the time the basis didn't match the calculated balance.

Or at the very least add this as an option in settings for the end user to decide when they want a notification as they see fit.
