Try pulling the acknowledgments through by going to EF Center -  highlight the returns you are having issues with then instead of Receiving Acknowledgments do the Update Acknowledgment Status.

I've had to do this with some of my returns.  And there are several posts discussing same problem.

Thank you but I had already done that and nothing.  BUT this morning the corporation was accepted.  Still waiting on the personal.

@dkhAre you having problems with Maryland?. No acceptances after about noon from Maryland yesterday

I don't do Maryland returns. I had issues with some Federal and Indiana returns.    

@dkh  thank you

You're welcome @chasetax 

Received this today.  Curious as to who was slow to notify...OK or Proseries?  Oh well.  It was accepted.
