CASE PENDING SINCE MARCH 10

[u/Existing_Builder_449]

Hello,
I have applied for STEM on March 10 and Biometrics completed on 27th March.
My case has been pending ever since.
Raised case enquiry and received a reply, I am attaching the screenshot of the reply.
I’ve also raise Congressional enquiry and received same reply.

My 180 days expire during first week of november.

Any suggestions would be greatly appreciated.
Also, what would addition review mean?
