Yes, this is what I've noticed too. Students here got study permits within 2 weeks. But hardly any April TRV applicant has received a PPR. (Applied from KSA in April 2022)
14th April 2022 - Application
18th April 2022 - Biometrics
Applied from KSA
Sent a webform, but received a generic reply after a month
No other update. Still waiting...
No, I am still waiting. But two students I know received their study permits within 2 weeks of applying (they applied from Khobar). So clearly, IRCC is prioritizing study permits rather than TRVs.
I have a similar issue. I applied using GCKey Portal on 18th April 2022. (Applied from Khobar, KSA) No update till now. But my daughter applied in March 2022 and got her study visa in 19 days!
