I am actually dealing with this situation myself. 16 clients. They were all accepted by the IRS when I do the Status update, but nothing being updated in their files.  I've done the Efile update acknowledlement status (multiple times now), but it doesn't update anything.  And I have no 9325 form with the the submission ID for any of them.  All of their returns were accepted between Mon 3/22 and Fri 3/26.
