Pending S041 form from HMRC

Hello, I am a EU citizen and worked for several years in the UK during which I made monthly NI contributions. This started before Brexit so I fall under the withdrawal agreement. I’m back to my home country (Portugal) and need the UK to send/confirm my NI records in order to be eligible for maternity leave pay. The Portuguese social security has requested my S041 (E104) to the UK through EESSI in late January/early February, but despite them having insisted a couple of times, HMRC has yet to respond to the request. Unfortunately, until HMRC responds, my process (and maternity pay) cannot move forward. Is there anything I can do to speed up the process, besides asking for updates from the PT’s social security which I have? Is there a way to track the status of a request made through EESSI (I have the request’s international ID number) or follow up with HMRC on this? I appreciate any help on this. Many thanks!
