Your timeline is similar to mine. I sent RCMP on March and is still as submitted. I did upfront medical last monthI don’t know. Probably not yet.
It is still showing as “Submitted” so I think they haven’t reviewed it yet, but 4 months after I submitted my spouse’s RCMP check and the RPRF payment I got MR, I don’t know if that means they worked on them before requesting MR or not. Lol.
IRCC drives everbody nuts. Lol.
