EAD/AP Combo card renewal receipt number not valid

[Sierra Echo 11]

Hi All,

 

While I haven't heard of I-485 interview yet, I sent EAD/AP combo card renewal to USCIS two weeks ago.

 

And today I got 2 text messages that my case was received.
I entered the two receipt number (which starts with 'IOE') on USCIS tracking page, however, only I-765 receipt number can be checked.

Each time I try to enter the other receipt number (which I assume it is my I-131 case), it returns an error message as below.

 

    "Validation Error(s)
     You must correct the following error(s) before proceeding:
     You are attempting to add a receipt number that does not exist in My Case Status. Please check your receipt number and try again."

 

I triple checked my receipt number, and it is correct.

Anybody has same issue?

Problem solved.

I called USCIS, was transferred to tech support team, and the tech person provided me access code to enter my receipt to DHS's USCIS webpage.
