Hi!!!That's not true, in fact I have seen multiple times that they started working on stucked cases after GCMS notes are ordered. They will definitely know that you have ordered GCMS notes, but thats no issue.
My case is similar to yours. I'm also March AOR and stucked at IP2. I know many people from April who have received PPR two weeks ago. I'm the primary applicant, but my husband worked for government, so I suspect that they might have put yours and mine application for "security screening". I've ordered GCMS notes, but it'll take at least 3 more weeks until I receive them. Do keep in touch if you receive any update, I'll do the same.
Any updates since then?
