PAL, or Pre Arrival Letter, is intended for outland applicants. However, if you read through this thread, inland applicants also receive PAL (not all inland though). I received PAL in Dec 9, 2022 (I am inland applicant) and MP in Dec 16, 2022. After that, no updates until now. IMHO, PAL means nothing until you get portal 1. Just my opinion.
Also, when did you submit your application? Some applicants are lucky they have their application processed faster than EE. While some are unlucky enough to wait for more than a year in their application without any updates. It is all a crazy waiting game for Non-EE PNP applicants.
