Yes, if you follow this thread - Passport Return from CPC Ottawa - you can see many of us had these delays.
I sent mine in March and got passport back around June/July. Some of them got it even later than me.
As to travel before CoPR expiry…
Saw in a few forums and chat groups that IRCC is also giving electronic CoPR if the current one expired and unable to travel due to COVID.
From multiple forums, I have seen that folks have gotten a (generic?) response from IRCC advising them of writing back to IRCC when the applicant(s) are able to travel.
