Yeeeah.. I'm not sure I'd trust that website. I've seen quite a number of applications with AoR in Feb/Mar 2022 already get their CoPR. I submitted in May and don't have mine yet, but also saw some who submitted after me get theirs. There really seems to be no rhyme or reason.
Do you check MyImmiTracker? I use it a lot to see if other applications are being processed.
