APEX$ROW_STATUS is only relevant to rows in interactive grids and (historically) tabular forms. It is not supported on DML Form regions and so is returning null on the form page.
The form page process would need to use PK and/or :request values to determine which DML operation is to be performed.

Thanks!
I changed my PK to be the app_id. For now, just to test, I removed all conditions and made it simply an update. I even tried setting the page number of the values, but the code basically never touches the table (with or without the page number). There's no error, nothing is updated though.
update PLP_PLUSLOANPROC_X
set PLP_USER_ID = :P3_PLP_USER_ID,
PLP_COMMENTS = :P3_PLP_COMMENTS,
PLP_COMPLETED_STATUS = :P3_PLP_COMPLETED_STATUS
where PLP_APP_ID = :P3_PLP_APP_ID;

I'm obviously misunderstanding something.

What is logged when the page is submitted in debug mode?

I figured it out. It was a dumb mistake. I hadn't set the execution options to be "once per page visit" instead of per session.
Thank you!
