Hi Chef,
I was on implied status for some time during PR processing. Per my understanding if you travel outside during implied status you will lose your implied status- and that means you will become ineligible for PR with your current ITA.
And also, I did say that you can switch jobs AFTER you get the open work permit approved, that is, once you are no longer under implied status- but your status is confirmed.
Do read my response again and you will see that I've said the exact same thing about BWOP
