Yes, my EAD expired on July 20th. USCIS received my application on March 14th. I have followed all the steps listed in the PD to no avail. The only piece of news I received from the Ombudsman office was the following:

"The CIS Ombudsman's Office received an update from USCIS informing your case is still being actively reviewed. USCIS is not sure how long the review will take but will continue to provide the Ombudsman’s Office with updates.

As the updates are received, you will be notified. We hope that you find this information to be helpful and thank you for your continued patience."

I will update this thread once I receive further news. However, do not count on any of these resources to expedite your DACA-EAD renewal because USCIS will not do so. Unfortunately, we are at their mercy and there is nothing to do but wait.
