Dear
You can call to IOM center from where you did your medicals and ask about your medical reports and they will share your over medical results status. Applicants also shared that IOM only send results to LVO when it is cleared and in case of any issue, IOM stopped results and called the applicant again for further recommended testing so as your ecas status changes Inshallah everything will be alright but still if you want further confirmation then call to IOM and ask result.
Regarding PPR request, you can see above updated chart and can get idea for PPR request dates after MR, I hope it will be helpful.
Regards,
Raza
