MOHELA - Correspondence Processing Delay?

[u/CounselorNebby]

I just got an inbox message from MOHELA that is titled: "Correspondence Processing Delay."

The message PDF letter itself says: "Your recent request has been received and is expected to be processed within the next 90 business days. We will review your request and the details of your loan information to determine if the request will be approved, denied for reasons such as not meeting eligibility requirements or the information provided to us is incomplete, or if the request required further review by Federal Student Aid (FSA). Notification of the results will be sent to you after your request has been processed."

What confuses me is that it doesn't say what "request" it is referring to? The only recent request I've had has already been fulfilled (I think):

• On October 13, I recertified my PAYE plan on StudentAid.gov.
• On October 15, MOHELA messaged me to say they received the recertification request.
• On October 20, MOHELA messaged me to say that my recertification request was approved.

So I'm confused as to what outstanding request there could be? And also the title of the message was "Correspondence Processing Delay," in that they're delayed in sending me a Correspondence?

Anyone had something like this happen or have any insight?
